摘要/Abstract

摘要： 针对现有电网评估模型未考虑源荷不确定性情形以及并未关联电网响应不确定性的运行策略的不足,提出适应源荷不确定性的参考电网区间优化方法,为实现柔性电网规划提供理论参考。基于规划周期内不确定电源、负荷预测区间和规划网络候选方案,充分关联电网运行策略,构建以追求电网的发电成本、备用配置成本和输电网络投资成本总和最小为目标,以不确定性背景下电网各种工况运行安全域为约束条件的参考电网区间优化模型,并给出模型求解方法,得到支撑源荷功率平衡的电网优化方案。通过算例分析说明了所提方法的有效性。

Abstract: Aimed at the shortage of the existing reference network models that rarely take the uncertainties of power sources and electric loads as well as the operation strategies of responding uncertainties into consideration, an interval optimization method for reference network adaptable to the uncertainties of power sources and electric loads was proposed to provide theoretical guidance for flexible electric network planning. Based on the forecasted interval level of uncertain power sources and electric loads in the planning period and candidate schemes in network planning strategy, a novel interval optimization model for reference network was built to minimize the total generation cost, reserve allocation cost and transmission investment cost, in which the security region constraints under all operating modes should be respected. The solution method was given for the proposed model to get the optimal planning scheme for electric network. Finally, case studies were conducted to demonstrate the effectiveness of the proposed method.

Key words: reference network, interval optimization, flexible electric network planning, power grid evaluation, electric network operation strategy
