考虑电力交换的区域电网新能源承载能力测算方法

A Calculation Method for the New Energy Carrying Capacity of Regional Power Grid Considering Power Exchange

在测算规划年各分区的新能源装机基础方案的基础上,通过电力电量平衡计算,为规划年份潮流计算提供基础,再通过潮流计算结果、“N-1”校核,依次确定丰小方式和丰午方式下区域潮流外送断面卡口,进而确定丰小方式和丰午方式下区间电力流交换与区内风电装机承载力、光伏装机承载力的影响关系。提出考虑电力交换的区域电网新能源承载能力的测算方法,该方法能切实提高新能源承载力测算结果的适应性,为电网网架结构和电源结构的规划与建设提供更为科学的依据。

This paper provides the basis for the power flow calculation in the planning year through the power balance calculation of new energy installations in each district.Finding the cross-section bayonet of regional power flow under Fengxiao mode and Fengwu mode,on the base of the power flow calculation results and"N-1"check results.Then further research the relationship between regional power flow exchange and regional wind power installed capacity and photovoltaic installed capacity.This paper proposes a calculation method for the new energy carrying capacity of the regional power grid,considering the power exchange.This method can effectively improve the calculation adaptability,and provide a more scientific basis for the planning and construction of the grid structure and power structure.
