Corpus ID: 112172290 Impact of Large-Scale Wind Farm Connecting With Power Grid on Peak Load Regulation Demand @article{Ning2010ImpactOL, title={Impact of Large-Scale Wind Farm Connecting With Power Grid on Peak Load Regulation Demand}, author={Zhang Ning and Tianrui Zhou and Chang-gang Duan and Xiaojun Tang and Jian
In the peak load regulation scenario, the main circuit of the power system includes four components: the wind field, the energy storage system, the load, and the thermal power unit. The power system must maintain power balance at all times.
Based on (1a), (1b), we summarize that the factors of determining the peak-regulation capability of a power grid include: (1) the boundaries of dispatchable ranges of units; (2) the on–off states of slow-startup units; (3) the upward and downward reserve demands; (4) the peak and valley load of power grid, as shown in Fig. 1.
In order to mitigate the above contradiction and reduce the peak–valley difference of power grid, peak regulation is needed. This paper mainly focuses on the
