面向用户需求的DG与配网网架多目标联合规划
摘要：考虑电力用户的多样化供电需求和可再生能源DG出力随机性,提出了面向用户需求的DG与配网网架多目标联合规划方法。根据用户对供电电压质量和可靠性等多样化的需求,对负荷需求整理分类;根据可再生能源DG出力的概率模型和机会约束规划方法,处理不确定性问题;以年社会成本、电压偏移率和用户停电缺失量综合最优为目标函数,建立了DG与配网网架多目标联合规划模型。基于pareto优化理论,采用多目标混合粒子群算法和熵权修正的AHP-TOPSIS多属性决策策略相结合的方法,求解模型。最后,利用算例验证所建模型的合理性和有效性。
Abstract:By considering the diverse power supply demand of electricity user and the stochastic characteristics of the DG power output, a multi-objective joint planning method for user demand-oriented DG and distribution network framework is presented. To meet the diverse demand for voltage quality and reliability of power supply, the load demand is classified. According to the probability model of renewable energy DG power output and chance-constrained programming method, the uncertainty problem is solved. With the comprehensive optimization of annual society cost, voltage deviation degree and power user outage loss as objective function, the multi-objective joint planning model for DG and network frame is built. Based on pareto optimization theory, the model is solved by using TOPSIS multiple-attribute decision-making strategy that combines the multi-objective hybrid particle swarm optimization algorithm with the AHP and entropy weight modified method. In the end, the rationality and validity of the proposed model is verified by numerical calculation example.
