基于Pareto支配法的微电网多目标能量优化短时调度策略研究

Study on Short-Term Scheduling Strategy for Multi-Objective Energy Optimization of Microgrid Based on Pareto Domination

微电网中存在风力发电、光伏发电等微电源,其发电的波动性限制了微电网调度的跟随性和实时性。因此,使用储能装置对波动性微电源进行功率平抑,以降低其接入微电网时的波动性,确保微电网短时调度的可行性。微电网短时调度考虑从技术、经济和环境等方面对各类微电源进行能量优化配置,并使用Pareto支配法对微电网多目标优化问题进行了求解。对单步求解生成的Pareto解集,使用权重系数法、附加目标法和调度空间法进行了调度方案筛选,确定了短时调度情况下的调度策略。

There are micro power sources such as wind power generation and photovoltaic power generation in microgrid, which limit the following and real-time performance. Therefore, energy storage device is used to stabilize the volatility of micro power, which ensures the feasibility of micro power network short-term scheduling. Microgrid short-term scheduling optimizes the energy allocation of various types of micro power in technology, economy, environment and other aspects. To solve the multi-objective optimization problem of microgrid, an Pareto domination method is used. The Pareto solution set is generated by every single step. By using the method of weight coefficient, additional target and scheduling space, the scheduling scheme can be selected.
