兼顾用户满意度和发电侧收益的微电网系统量子粒子群优化

兼顾微电网系统发电侧与用户侧的综合利益,从能量管理的角度出发,建立了以用户满意度和发电侧收益为目标的优化模型。首先,采用多目标局部变异-自适应量子粒子群算法(Multi-objective local mutation adaptive quantum particle swarm optimization,MO-LM-AQPSO)获得用户满意度及发电侧收益的Pareto前沿。然后,引入缺电损失,以发电侧收益最大为目标,选取了非支配解中的最优解,并通过算例仿真验证其有效性。进而引入可平移负荷及分时电价激励机制,通过合理的峰谷电价比以引导用户积极参与需求侧响应。仿真结果表明,合理的激励措施,可提高微电网收益和用户满意度实现可再生能源的最大化利用及蓄电池运行损耗的有效减少。

Quantum particle swarm optimization for micro-grid system with consideration of consumer satisfaction and benefit of generation side

Considering comprehensive benefit of micro-grid system and consumers,we establish a mathematical model with the goal of the maximum consumer satisfaction and the maximum benefit of power generation side in the view of energy management.An improved multi-obj ective local mutation adaptive quantum particle swarm optimization (MO-LM-AQPSO) algorithm is adopted to obtain the Pareto frontier of consumer satisfaction and the benefit of power generation side.The optimal solution of the non-dominant solution is selected with introducing the power shortage and power loss to maximize the benefit of power generation side,and its reasonableness is verified by numerical simulation.Then,translational load and time-of-use electricity price incentive mechanism are considered and reasonable peak-valley price ratio is adopted to guide users to actively participate in demand response.The simulation results show that the reasonable incentive mechanism increases the benefit of power generation side and improves the consumer satisfaction.Also the mechanism maximizes the utilization of renewable energy and effectively reduces the operation cost of the battery.
