【Abstract】 Given the peak-shaving demand of a wind power delivery type grid, the electric heating optimal configuration method of a peak-regulating virtual power plant considering a wind power delivery protocol is proposed. First, the structure and interaction consumption mechanism of the power grid with a wind-power delivery protocol is analyzed.From the energy consumption characteristics of regenerative electric heating, a demand response model of regenerative electric heating is established on the basis of quantitatively deducing its adjustable characteristics. Then, with the objective of optimal economic performance in the regional power grid with the wind power delivery protocol, the electric heating capacity optimal allocation model of the VPP is established. This combines the peak-shaving strategy of thermal power units and VPP. A regional power grid in Heilongjiang Province is selected for analysis, and the results show the correctness and effectiveness of the method.更多还原
