Battery Storage will have a Profound Impact on Smart Buildings
Often the best ideas are the most simple and elegant. If electric vehicles and consumer devices can have battery storage why can’t buildings? And if buildings can pull electricity from the grid at off peak times and store it in batteries, wouldn’t that save money? Since 2009, Stem based in California, have been working on these questions and disrupting the energy storage industry. ...

How big is the distributed energy opportunity for water and wastewater utilities?
Energy costs for water utilities are large, and growing Energy is a significant cost for many water utilities, and costs are growing as more energy-intensive forms of water supply, including desalination, are being used. Energy is typically the second-largest utility budget item in developed countries, after labour. In many developing countries, energy can account for 70% or even more, of annual ...

Application of DC meters in PV power generation.
Application of DC meters in PV power generation. PV power generation systems convert solar energy into electrical energy by utilizing solar panels. This type of energy is clean and does not rely on conventional energy sources. PV power generation systems comprise solar panels, controllers, inverters, DC power supplies, and energy meters. The use of DC meters in PV power generation is very ...

Assessing the benefits of a provision of system services by distributed generation
Distributed Generation (DG) units are said to have the potential to become an integral part of the future power systems. Today, DG units are characterised by high specific investment costs, but nevertheless are politically promoted because of their high degree of energy efficiency and their capability of reducing the current dependency on fossil fuels. However, at longer term DG units have to ...

Control and protection of distribution systems with distributed generators
Unquestionably, in the last years, the number of generators connected directly to electric power distribution systems has increased. In addition, the main statistics and signals show that such tendency could become even more intense in the coming years. As a consequence of this policy, many technical factors related to control, protection, operation and analysis of distribution systems should be ...

How Artificial Intelligence helps companies become more sustainable
Some time ago, I wrote a blog about how sustainability and digitization go hand-in-hand. I mentioned the power of Artificial Intelligence (AI) to help us make smarter decisions that rely on hard facts and enormous amounts of data - providing companies operational benefits and supporting us on our path to sustainability. But there’s a catch: To be future-ready, companies must start ...

Power conditioning of an uncontrolled micro-hydroturbine-driven induction generator for distributed generation using a battery energy storage system
Distributed Generation (DG) and its interconnection to the AC power grid is a relatively new concept. DG employs small generators, which are distributed throughout the power system. The electricity is usually generated by renewable energy sources such as wind, hydro and tidal, which are intermittent in nature. These generators connected to the AC grid may lead to severe power quality problems. ...

Reactive power compensation of wind energy conversion system by using Unified Power Flow Controller
Voltage control and reactive power compensation in a distribution network with embedded Wind Energy Conversion System (WECS) represents the main concern of this paper. The WECS is a fixed speed/constant frequency system that is equipped with an induction generator driven by an unregulated wind turbine. The problem is viewed from short-term (10 seconds), mid-term (10 minutes) and long-term (48 ...

Structure-preserving dynamical model and distributed stabilisation of electricity infrastructures with renewable energy resources
This paper introduces a module-based approach to modelling and controlling electricity infrastructure with a high penetration of distributed renewable energy resources. Each energy-converting component is defined as a module and is represented in terms of its local variables and the interaction variables between the module and the transmission network. The structure of the electricity ...
