含高比例清洁能源的微电网多目标优化调度策略
摘要:高比例风光电源接入微电网系统，带来了更多的不确定因素，也给电网的优化调度带来了挑战。为提高系统的经济、环保性能，合理配置风光机组的装机容量，促进风光消纳，该文建立高比例清洁能源微电网模型，定义经济性与环保性目标函数，提出多目标优化调度策略，并采用粒子群优化算法进行求解。通过算例分析，探究清洁能源渗透率对微电网的经济、技术特性及清洁能源消纳率的影响。随着清洁能源渗透率的提高，消纳率总体呈降低趋势，且存在渗透率临界值，在临界值范围内提升渗透率可有效提升微电网综合运行效益。结果表明，该文提出的调度策略正确有效、算法收敛可靠，能为风光机组装机容量的合理配置提供重要参考。

Abstract：The high proportion of wind-photovoltaic power supply connected to microgrid system introduces more uncertain factors, which brings challenges to the optimal dispatching of power grid. In order to improve the economic and environmental performance of the system, rationally allocate the installed capacity of the wind and photovoltaic units, and promote the consumption of the wind-photovoltaic energy, this paper establishes a high-proportion clean energy microgrid model, defines the economic and environmental objective functions, proposes a multi-objective optimal scheduling strategy, and uses particle swarm optimization algorithm to solve the problem. The influence of clean energy permeability on the economic and technical characteristics of microgrid and the consumption rate of clean energy is explored through the analysis of examples. With the increase of the permeability of clean energy, the absorption rate generally shows a downward trend, and there is a critical permeability value. Increasing the permeability within the critical range can effectively improve the comprehensive operation efficiency of microgrid. The results show that the proposed scheduling strategy is correct and effective, the algorithm convergence is reliable, and it can provide an important reference for the rational allocation of the installed capacity of wind and photovoltaic units.
