文中针对并网型微电网优化运行问题,在充分考虑微电网中需求侧资源的前提下,建立了含风机、光伏、微燃机和储能系统的并网型微电网经济优化调度模型.模型中结合分时电价和需求响应中的可转移负荷,并考虑储能寿命损耗和安全运行条件.构建以系统运行总费用最小和系统净负荷最小的多目标函数.采用遗传算法,通过MATLAB对所提模型进行求解,算例结果表明文中提出的模型在充分考虑可转移负荷和储能实际运行损耗的前提下,实现微网的经济运行.

Optimal Dispatch of Microgrid Considering Demand Response and Comprehensive Battery Loss

Aiming at the optimization operation of the grid-connected microgrid,this paper takes into consideration the demand-side resources in the microgrid,and establishes an economic optimal dispatching model for the grid-connected microgrid including wind turbines,photovoltaics,microturbines and energy storage systems.The model combines time-of-use electricity prices with transferable loads in demand response,and considers energy storage life loss and safe operating conditions.Construct a multi-objective function that minimizes the total cost of system operation and minimizes the system load.The genetic algorithm was used to solve the proposed model through MATLAB.The results of the examples show that the model proposed in this paper can realize the economic operation of the microgrid on the premise of fully considering the transferable load and the actual operating energy storage loss.
