The ability to operate effectively on electricity spot markets relies on the capability to devise appropriate bidding strategies. These in turn can benefit from the inclusion of a reliable forecast of short term system marginal prices (SMPs). In a market with an increasing percentage of renewable generators, reliable forecasts must necessarily consider additional factors such as meteorological forecasts,...
Smoothing output power and alleviating mechanical loads are two main control objectives for wind energy conversion system (WECS) above rated wind speed. Conventional control methods, such as PID, cannot handle and balance multi-objective control problems. This paper presented a multi-degree of freedom, multi-objective optimization control method using model predictive approach to solve these problems...
Electricity markets are different from other markets as electricity generation cannot be easily stored in large amounts and in order to avoid blackouts, the generation of electricity must be balanced with customer demand for it on a second-by-second basis. Customers tend to rely on electricity for day-to-day living and cannot replace it easily so when electricity prices increase, customer demand generally...
In this paper, the control strategy to improve voltage stability of power system was studied after large scale wind power plants integrated. And the strategies to improve the transient voltage stability of wind power plants were introduced firstly. Based on the analysis of characteristics that voltage stability of the fix speed wind generator, a new control strategy that can improve the voltage stability...
