计及发电报价等影响因素下系统负荷裕度的求解

Load Margin Solution Considering Influencing Factors Such As Generation Bidding

建立了计及发电报价,静态负荷模型和静止无功补偿装置(Static Var Compensator,SVC)对求取电力系统负荷裕度影响的系统分析数学模型,并采用局部电压参数化的连续潮流算法求解电力系统的负荷裕度。在IEEE-30节点测试系统上的仿真结果表明,同时计及上述3种影响因素下的负荷裕度,与不考虑这些影响因素时所得到的结果对比分析表明了求解电力系统负荷裕度时,考虑这些影响因素的必要性和合理性。

This paper presented a mathematical model. In this model, the principle of generation distribution based on generation bidding, static load model with polynomial expression of exponential form, and Static Var Compensator were involved. A locally parameterized algorithm based on continuation power flow was proposed to get load margin of power system. The proposed algorithm has been studied on IEEE-30 bus system. Comparing with results without considering these influences, it demonstrates the necessity when gaining load margin of power system.
