Research on Peak Load Regulation Demand of Power System with Large-Scale Wind Power Integration

In china, increasing large-scale wind power integration has brought much more peak load regulation demand, which is the bottleneck of the integration of wind power to systems. This paper analyzed the influence mechanism of large-scale wind power on peak load regulation demand. And critical indicators are constructed based on the daily peak-valley difference to evaluate peak load regulation demand caused by wind power integration. Statistical analyses based on large number of actual dates reflect the influence of large-scale wind power integration on peak load regulation demand, which can help provide more decision-making information for planning and operation.
