Make green energy more efficient, reliable and safe - Case study
Distributed, intermittent renewable power sources create natural load and phase imbalances at the interconnect to the grid. This results in a degradation of efficiency (loss of revenue), equipment life (higher replacement costs), and power quality (“dirty power” that damages rate payer electronics). These effects represent increasing challenges as the percentage of renewable sources ...

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 ...

Development of PSO-based robust controller for maximising wind penetration
In this paper, a new robust controller has been proposed for attaining the maximum safe instantaneous wind penetration. Particle swarm optimisation (PSO)-based algorithm has been developed to obtain the maximum safe instantaneous penetration by the optimisation of grid parameters. The developed algorithm has been tested on modified IEEE 14-bus system. The effectiveness of the proposed methodology ...

A dynamic virtual power station model comprising small-scale energy zones
Concerns over global warming and high oil prices are expected to lead to a continuous increase in electricity generated by distributed renewable energy sources and small-scale embedded generators (SSEGs). This increase in SSEG will pose numerous technical challenges for distribution network operators. The small-scale energy zone (SSEZ) concept seeks to overcome these challenges using appropriate ...

Biofuel CEOs Send Letter To President Obama Over EPA RFS Proposal
On September 16, 2015, 23 biofuel executives sent a letter to President Obama regarding the U.S. Environmental Protection Agency's (EPA) Renewable Fuel Standard (RFS) volume requirement proposal. The revised RFS allows companies to challenge the distribution requirement of renewable fuel, potentially resulting in RFS requirements being waived on a year-to-year basis. The letter outlines the ...

Development and opportunities of distributed generation fuelled by renewable energy sources
The key issue to the widespread of distributed generation (DG) is the ability to safely, reliably and economically interconnect new energy sources with the existing distribution network 'utility grid'. With the rising prices of petroleum fuel sources, a high expected penetration of renewable energy sources (RES) such as wind and solar as part of the emerging DG fuel resource are expected to be ...

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 ...

Cascade failures and distributed generation in power grids
Power grids are nowadays experiencing a transformation due to the introduction of distributed generation based on renewable sources. At difference with classical distributed generation, where local power sources mitigate anomalous user consumption peaks, renewable sources introduce in the grid intrinsically erratic power inputs. By introducing a simple schematic (but realistic) model for power ...

Rhode Island: little state, big energy efficiency opportunity
Rhode Island is often the butt of jokes about its size, a lot of them having to do with an inability among residents to screw in electric light bulbs. But when it comes to energy policy, the state has often loomed large, even if few people notice. For example, it was Rhode Island that led the way with electric industry restructuring in the 1990s. California and Massachusetts usually get the ...
