Reserve Demand Determination Method Considering the Different Time Periods Uncertainty of Wind and Solar

With the gradual realization of China’s 14th Five-Year Plan, proportion installed renewable energy capacity in all regions has increased significantly. The access a high brought serious challenges to safe and stable operation power system. uncertainty wind photovoltaic output makes it difficult for traditional reserve demand determination method economically effectively calculate required by system, so is urgent propose reasonable method. On one hand, ensures that deserve needed system sufficient cope with real-time active fluctuations, on other improves economy capacity. considering different time periods solar this paper able meet new At last, article proves benefits Reserve Demand Determination Method through numerical example.
