Optimal operation method of wind farm with demand response

摘要

In order to solve problems of global warming and depletion of energy resources, renewable energy systems such as wind generation is getting attention. However, wind power fluctuates due to variation of wind speed, and it is difficult to wind power forecast perfectly. Therefore, wind power developers should follow the strict condition for output power smoothing when wind turbine generators (WTG) are installed in a power system. To overcome the issue, several reports have been published regarding integrations of a battery energy storage system (BESS). However, integrating large batteries with wind plants as a result, increase cost for the power system. Meanwhile, all electric apartment houses or residence such as smart houses are increasing. Load control in these demand may contribute smoothing the wind power fluctuations. This paper describes an optimal operation method of wind farm (WF) incorporated demand response (DR) taking into account wind power forecast error. The optimization purpose is to smooth the output power fluctuation of the WF and to obtain more benefit for electrical power selling.
