Total optimization of the energy production

Energy Opticon offers one of the most popular and fastest-counting system, Energy Optima 3, for online computer optimized production plans. The system automatically calculates how facilities shall be operated to minimize costs and maximize revenue.

Energy Optima 3 works with a total optimization, meaning that the electricity production and the district heating production are optimized together, a necessity for production companies working with co-generation.

Follow-up of the production economy

Exact optimizations and forecasts are crucial to maximize efficiency and profit. Analyzing the past shows how far the reality is apart from the theoretical maximum. Energy Optima 3’s follow-up delivers individual solutions to analyze costs, forecasts and the production of each single unit in the past to find unused optimization and improvement potential.                            

This tool also offers automatic long-term follow-up that can be used for yearly economical goals.

Another important aspect is that it focuses the production staff’s attention on the production economy, and is a very powerful tool in achieving the profits from using the module for production optimization.

All types of facilities

Energy Opticon’s many years of branch experience enables modeling of all types of production facilities and all kinds of combinations of these. This is made possible through a topology editor program that allows customers to model and change in its power plant fleet. The customer can also change load forecasts, various contracts for fuel and more.

All types of special conditions and constraints can be handled either in the software itself or with special programming.

Saves milion per year

Independent studies have shown that with computer-optimized production plans, it is possible to lower variable production costs by 2-10 % per year. With the current conditions in the electricity markets, and with the possibilities to also optimize the district heating network, the savings could be even higher (higher revenue). Moreover, it is today a mere necessity of this type of computer tools in order to act successfully on the electricity market, since the changes happen too quickly in order to be able to figure out the production plans manually or base the plans on simple rules of thumb.

Optimization calculations

The optimization horizon (how far ahead the optimization extends) is flexible and can be freely adjusted by the user. Optimizations can be started, for example, once per hour, but this can also be chosen by the user. A work flow engine can automate different optimization scenario calculations with, for example, different electricity prices and heat consumptions. 

All optimization results are saved in a database and can be transferred for further analysis.

Short-term and long-term optimization

The standard module for optimal production plans calculates with time horizons from 1 hour up to a month ahead of time (short-term optimization). With long-term optimization, optimization for up to a year is made possible. With year time horizon, calculations for fuel and audit planning, CO2 quotas, investment in new or modified units in the energy system, taxes that are based on long-term quotas etc. are made possible.

Hydropower optimization

Hydropower optimizations in Energy Optima 3 calculate the economically optimal operation of any type of hydropower stations. It includes run-river stations, pump storages and dams. Different time delays between different power stations in a river system are calculated and optimized as well as the water levels in the dams. It can also optimize the power balance from hydro power together with for example the power from thermal power plants. Provided that the electricity trading module is connected to the system, different types of electricity market products are taken into account in the calculations.

Regional cooperation

As the energy industry is constantly faced with increased challenges, energy companies need to find new ways to increase revenue and reduce costs.

A growing trend in energy companies with cogeneration is to initiate regional cooperation between different cities and owners. The local district heating networks are interconnected, thus increasing the flexibility of district heating systems and revenue for the sales of produced electricity and district heating, while providing the opportunity to handle the increase in complicated operating instances in production.

Especially when there is a system of waste incineration, this is a good solution, as waste incineration can sometimes even cause negative heat prices on the production side, which means that the cheap waste heat can reach more heat consumers.

In order to optimize the operation of several local district heating networks with different owners as a large network (which is complicated and includes many parameters), it requires a tool in the form of optimization tools. The companies need help to figure out which units to run, when and at what load. They also need to know the amount of heat to be transferred, as well as when and which of the companies should produce it.

To calculate which company should get what, there are different models.

One possible model is the trading model (calculations ahead of time). The trading model allows close cooperation between several parties that do not require a high level of trust between the parties. An example of this model is the cooperation in Copenhagen. In this cooperation, the first district heating forecast is made for the next 24 hours. After that, the existing producers offer optimized price steps with district heating and corresponding district heating. Price and offer are then accepted, or not.

In the recent years, 'deeper' co-operation has occurred in the regions, the trust model (calculations forwards and backwards). This type of collaboration enables even greater potential savings, profits, flexibility, energy security and other forms of cooperation. This also requires a high level of communication and transparency and a high focus on the production economy.

The Forecast module includes high quality forecasts for:

  • Energy consumption (e.g Electricity, Gas, Steam, District cooling) – Basis for planning of the heat and electricity production.
  • Electricity– Electricity price forecasts for different spot markets and also for reserve power on the middle European market
  • Wind and Photovoltaic power – Load forecasts with different quality/price options
  • Weather– Energy Optima 3 is improving the weather forecast from weather institutes

Additionally the user can create own forecasts and calculations using existing forecasts, factors or other mathematical functions. These forecasts can be used separately as well as a part of the optimization process in the Energy Optima 3 optimization system.

Advanced algorithms

Energy Opticon constantly develops the advanced algorithms, which build the foundation of the forecast calculation. The aim is to perfect the precision of the forecasts, not just under perfect conditions, but also in situations when measurements are faulty, late or missing. The result is a forecast that not only reaches very high precision, but also is also stable enough to function even when for example measurements are wrong or missing.

Accuracy and evaluation

The district heating load forecast in the Energy Optima 3 system contains advanced functions for forecast evaluation. This enables the user to compare the calculated forecast with load measurements, weather forecasts and weather measurements. Any deviations in the load forecast or the weather forecast precision are immediately revealed.

As part of the service agreement between the user and Energy Opticon, the precision of the load forecasts is regularly monitored by Energy Opticons forecast experts. Any deviations or irregularities found by Energy Opticon are immediately pointed out to the user.

District heatING, DISTRICT COOLING AND GAS NETWORK load forecasts

It is very important for the production planning that the forecasts are accurate. The forecasts are indata to the production planning. To get good results, the indata has to be good. When the district heating load forecast is fluctuating a lot, it is interesting to know exactly when to start a new boiler, and which boiler, in order to avoid unnecessary start and stop costs on the boilers.

Energy Opticon provides a very accurate district heating load forecast. The forecast is based on algorithms that are the result of many years of experience and developed in-house.

The forecast is calculated with 15 minutes interval (different intervals are possible). Therefore, Energy Opticon is able to provide continuous and current information to the planning staff, considering new conditions.

The district heating forecast can be used to manage the operation planning manually, or this can be done by using the production module in Energy Optima 3.

Electricity load forecasts

The electricity load forecast is using an adaptive approach and is recalculated every 15 minutes. The forecast is continuously improved by using historical data together with current online-measurements.

WHAT IS SOHN?

The Smart Optima Heat Network (SOHN) module is a software tool that helps district heating producing companies to economically optimize the forward temperature in the operation of its district heating network, based on adaptive and dynamic calculation models. 

CHALLENGES FOR ENERGY COMPANIES

All the economically important components of the district heating network are modelled and the economically optimal operating scenario is calculated.

The new module takes into consideration:

  • Heat storage in the district heating network
  • Time delays in the network
  • Heat losses
  • Transmission constraints (bottle necks)
  • Temperature dependent efficiencies for steam turbines and flue gas condensers 

The district heating network is dynamic in nature such that a change in flow rate affects the entire network within a few seconds. However, it may take several hours for a change in forward temperature to reach the entire network. Smart Optima Heat Network utilizes this phenomenon and allows working with the dynamics of the network instead of against it.

SOLUTIONS AND BENEFITS

The result of optimizing with the Smart Optima Heat Network are:

  • Fewer start/stop of production units, resulting in economical savings and reduced wear of units.  
  • Lower CO2 emissions, as fossil fuels are often used during start-up of boilers. In addition, it is often fossil fuel that is used in peak load boilers that starts at temporary load peaks, which now can be avoided.
  • Better management of transmission constraints in the district heating network, so that heat produced with lower cost can reach larger parts of the heat network
  • Less water flow fluctuations in the network by adjusting the forward temperature to current time delays so that the right temperature reaches the consumers.

Energy Optima 3 Cloud provides the possibility to access the entire system of total optimization of economic energy production at a cost-effective level without high costs for own servers, IT competence or large investment costs.

Regardless of the size of energy system or company, you have the opportunity to access Energy Optima 3 wherever you are - by your computer, at mobile phone or tablet.

Energy Optima 3 focuses on the needs of traders working with the current market demands under a constantly rising time pressure. With standard solutions for individual scenarios, Energy Optima 3 optimizes:

  • Long-term volumes

  • Spot Day-Ahead market
  • Spot Intraday market

  • Reserve Power

  • Balance Power

  • All kind of energy types

  • Internal and external suppliers and demands

Confirmed optimization results or data stays in the system and is taken into consideration in following optimizations if required.

The progress of renewable energies with higher capacities of wind and photovoltaic energy have led to very intensive changes on the electricity market:

  • Electricity prices show strong fluctuations, which requires good electricity price forecasts

  • The electricity balances in electricity grids become unstable due to the uncertainty in influx of the wind and solar radiation. This has led to that the need for services for reserve power has increased, especially in Central Europe

The Energy Optima 3 Trading Module is therefore mainly focused on trading of electricity, but can also be used for trading of other forms of energy.

Electricity price forecasts

Energy Optima 3 includes electricity prices forecasts for the day-ahead spotmarket with prices for each hour of the next few days in the total optimization. This forecast is then the basis for day-ahead electricity trading on the power exchange.

Reserve power

Energy Optima 3 handles all the three types of reserve power traded in the markets for balance power:

  • Primary
  • Secondary
  • Tertiary

This includes the handling of specific national rules for the lengths of bids for balance power, as well as price forecasts for balance power.

Total optimization

In optimizations that include the trading module, all the ingoing components of the total economy are optimized:

  • Own electricity production

  • Deliveries on contracts and the demand for district heating, steam and other energy types

  • Sales and purchases of various market products in the electricity market as day-ahead, intra-day and balancing power

Advanced Reporting with Business Intelligence concept consists of two parts:


Import/Export of data: With this solution Energy Opticon can offer a wide range of possibilities and high flexibility about the import and export of data to and from Energy Optima 3. The tool allows customers a maximum level of handling changes themselves.

Visualization of data: Individual visualization of data from the Energy Optima 3 system. Energy Optima 3 users can set up own reports showing the information of interest in a personally configured format. It is also commonly used for showing follow up data such as economic follow up and forecast follow-up.

Simulations

An important function is the access to simulation databases. A simulation database is a separate database besides the normal “sharp” database. The simulation database is used for making own sce-narios for weather and load forecasts in order to evaluate how these variations influence the result of the calculations. It can also be used for making evaluations of the economical results of changes in the energy system.

Automatic calculations of load forecasts and optimized energy production plans demand accurate and safe management and validation of measurements. Most other modules in system depend on measurements. For this reason, the Measurement Module is the natural center of the Energy Optima 3 system.

The module connects to the local measurementsystem and imports measurement data for production and weather that is needed for the system. The module has a advanced toolset for standardized interfaces to the local measurement systems that handle csv files, ODBC (SQL),  OPC, PGIM, etc
