摘要:

针对微网孤岛运行模式下的优化调度,从经济性和可靠性2方面考虑,提出在传统微网经济调度模型中加入综合评估模型,得到不同侧重目标下的最优调度方案。首先,在热电联产的微网结构上,建立了包含运行成本最低和负荷缺电率最低为目标函数的微电网优化调度模型;其次,考虑到不同目标之间存在的矛盾,应用多目标粒子群算法结合调度策略,在MATLAB环境下对所建立的优化调度模型进行求解,得到一系列Pareto最优解;最后,通过利用基于层次分析法的综合评估模型对Pareto解集进行评价,再结合实时需求分析,为决策者提供最优调度方案。算例通过对某孤岛型微电网进行分析,验证了模型的可行性和实用性。

Abstract:

 To deal with the optimized dispatching of a microgrid working in the isolated island mode, taking economic efficiency and reliability into consideration, this paper adds comprehensive evaluation into the economic dispatching model of traditional microgrid to get optimal dispatching scheme with different targets. At first, we construct the optimized dispatching model of microgrid with taking the lowest operation cost and the lowest load deficiency rate as target function, based on the microgrid with cogeneration structure. And then, considering the conflict between different targets, we apply multi-objective PSO (particle swarm optimization) algorithm combined with dispatching strategy to solve the proposed optimized dispatching model in MATLAB, in order to obtain a series of Pareto solutions. At last, we use the comprehensive evaluation model based on the application of analysis hierarchy process to evaluate the Pareto solutions, and provide the optimal scheduling scheme for decision makers combining with real-time demand analysis. We verify the feasibility and practicability of the proposed model through the analysis example of an isolated microgrid.

Key words: isolated microgrid, multi-objective PSO, optimized dispatching model, analytic hierarchy process
