Powering Renewable Programs: The Utility Perspective
When considering how to build out a renewable energy portfolio, there are a lot of factors and many points of view to consider. For purposes of this narrative, we will take the point of view of the electric utility itself. Your electricity providers are quite familiar with the concept of a “smart grid.” According to the Department of Energy (DOE), a smart grid “generally refers ...

Free solar for Africa?
The African continent is not homogeneous. The constant gap between the way we perceive the north of the continent and the harsh reality that the South is going through is often surprising. Many start to see and praise the "African miracle” progresses. However, many obstacles remain for Africa to impose its way. The sun, is a natural, free and abundant wealth in the African land, would it ...

CSP and mining in Chile
With a mining industry that produces 35% of the world´s copper, it is imperative for Chile´s economic growth to produce energy from a source that is secure, dispatchable and unlimited. In an exclusive online webinar last week, hosted by CSP Today, experts discussed the positive impact that solar CSP could have on Chile’s mining industry. With many mining markets located in ...

CSP could be the best energy solution for the mining industry
Chile could be the make or break of the concentrated solar power industry in finding a way to work closely with the mining industry. Many mining companies in the Great North would greatly benefit from being able to take advantage of an abundant and free solar resource that could eliminate reliance on expensive energy imports. As part of the inaugural CSP Today LATAM conference, CSP Today has ...

State of the Smart Grid Business in 2013
Smart Grid sales across the world in the last 3 years at installed prices have grown by CAGR of approx. 35% and climbed to $36.5 billion in 2012. Given the general global economic demise during this period these figures are remarkable. However they include a steady flow of refurbishment business that has for more than 10 years incrementally improved and smartened up the control and reliability of ...

A practical transmission loss allocation methodology for deregulated power systems
In any power network, the cost of electrical losses constitutes a large component of network operating costs. As a result of introduction of competition under deregulation, it has become much more important to be able to determine a strategy for fair allocation of losses among the stakeholders. This paper suggests a quadratic loss formula with nodal power injections as independent variables. The ...

Cliffs farm wind turbine installation project – network connection and planning advice case study
Background F Culshaw. a diversified farm business at Cliffs Farm in Lancashire, sought advice from Envirolink Northwest about solving delays to its 2.25 MW wind turbine development on land at Cliffs Farm. Envirolink Northwest supported the client through contract negotiations with all parties concerned, and provided post planning consent advice. The advice given helped to achieve £50,000 ...

Price volatility forecasting using artificial neural networks in emerging electricity markets
In the adaptive short–term electricity price forecasting, it may be premature to rely solely on the hourly price forecast. The volatility of electricity price should also be analysed to provide additional insight on price forecasting. This paper proposes a price volatility module to analyse electricity price spikes and study the probability distribution of electricity price. Two methods are used ...

Combined heat & power is a clean, efficient and economic energy solution
The 21st century has highlighted a need for clean, efficient and economic energy, which has put Combined Heat & Power (CHP) into the limelight. By providing on-site power generation, waste heat recovery and system integration, CHP offers a realistic, near-term solution for exceptional energy efficiency and emission reduction. CHP systems can generate electricity locally while they recover ...

Key issues of tidal energy and factors affecting it globally with civil structures
This paper focus on some of the key challenges to be met in the development of marine energy, it present prototype form to being a widely deployed contributor to future energy supply of the world. Large-scale wave and tidal current prototypes have been demonstrated around the world, but marine renewable energy technology is still 10-15 years behind that of wind energy. However, having started ...

Reciprocally altruistic agents for the mitigation of cascading failures in power grids
Cascading failures in electrical power networks often come with disastrous consequences. A variety of schemes for mitigating cascading failures exist, but the vast majority depend upon centralised control architectures. Centralised designs are frequently more susceptible to communications latency and bandwidth limitations and can be vulnerable to random failures and directed attacks. This paper ...

Security assessment of the electricity infrastructure under terrorism
The electrical network is a critical infrastructure which is highly interconnected and strongly interdependent on other basic infrastructures on which basic human activities depend. As a result, this network is often targeted by terrorist attacks. The occurrence of events (that may affect the system) due to terrorism must be considered in power system security assessment. In this way, proper ...

The structure of electrical networks: a graph theory based analysis
We study the vulnerability of electrical networks through structural analysis from a graph theory point of view. We measure and compare several important structural properties of different electrical networks, including a real power grid and several synthetic grids, as well as other infrastructural networks. The properties we consider include the minimum dominating set size, the degree ...

Rural electrification by photovoltaic solar energy in Algeria
The economic and social development in Algeria in the last years has been in need of continues increasing in demand of electricity, especially in the isolated countryside. Solar energy represents a significant potential in Algeria, the country receives more than 3,000 hour of sunshine per year with a high level of radiation. The average of daily solar irradiation is from 5 to 7 kW hour m−2 the ...

Combined photovoltaic and energy storage systems: an integrated electrification solution for small islands
The numerous small Aegean Sea islands present serious problems related to insufficient infrastructure, low quality of electricity available at very high production cost, as well as problematic connection with the mainland. On the other hand, the high solar potential of the area may encourage photovoltaic-based applications characterised by rather low maintenance support demands. In this context, ...
