A synchronous generator is a key element in maintaining stability the traditional power system and performs well. However, high penetration of renewable energy will challenge stable operation future system, because characteristics converter-based resources differ from those generator. As result, weak grid caused by lack short circuit capacity inertia, damping, fault ride-through abilities become important issues for stability. To solve these problems, motor-generator pair (MGP) was proposed...
Increasing penetration rate of renewable energy sources makes it a trend for power system to be dominated by electronics, which brings challenges reliability and stability: first, unlike synchronous generator, converters do not have inherent inertia is important frequency response. Second, more complex interaction induced energies causes problems dynamics, example damping oscillation. In addition, cannot support high fault current, leading limitation some existing control schemes during...
High penetration rates of renewable energy will bring stability problems for the future power grid. One critical issues is lack inertia. In this paper, a synchronous motor-generator pair (MGP) system proposed as possible solution integration to enhance inertia and improve grid stability. First, feasibility studies MGP on inertia, damping, efficiency, cost are presented. Second, an analytical model established based its rotor angle relation. An active control scheme voltage phase difference...
The environmental problem is a major practical that China and the world are faced with. It trend for future power grid to be dominated by increasing penetration of renewable energy. However, high system may face many new problems, including reduced inertia system, stability frequency stability, weak characteristics output limit delivery capacity energy base. motor-generator pair (MGP) can deal with these problems efficiently, but current MGP control method still flawed. In this paper,...
With the increasing capacity of wind farm merged into grid, their impact on power system is also growing. It needs to establish an accurate and reasonable model. Large farms usually consist hundreds or even thousands turbine generators (WTGs). The amount computation will be huge if each WTG carried out a detailed So equivalent model for needed: classified based specific situations, then lumped number units. This paper adopts hierarchical cluster procedures classify farm, makes clustering...
With the development of concentrated wind power areas, new energy's dispatching problems are more prominent with its fast expansion.However, we can maximize utilization under curtailment conditions by optimal dispatching.The paper studies on basic theories turbines, and analyses power's control output characteristics turbine, which double-fed inductor generator's excellent decoupling reactive capability.By studying output, this provides a strategy for dispatch in generation.The calculation...
