摘要
将电动汽车电池集成到微电网可以为微电网提供额外的电能存储,其收益取决于市场电力价格、电动汽车充电状态和进站/出站率等因素。假设微电网由热力机组、可再生能源和含储能设施的停车场组成。文章提出了一种考虑电动汽车移动储能特性的能源管理优化模型,模型的目标函数是最小化预期的总运营成本,包括前期市场的能源购销成本、热力机组的启停成本及发电成本、电池的磨损成本以及在每个场景中与当地电力分销商进行电力交换的成本等。采用Benders分解算法对模型进行求解,并利用修改的14节点系统进行了仿真验证。仿真结果表明:利用电动汽车电池的储能特性有效地降低了微电网的总运行成本。
The integration of electric vehicle(EV)batteries into the micro-grid can provide additional energy storage for the micro-grid,the benefits of which depend on factors such as market electricity prices,EV charging status,and in-station/out-station rates.It is assumed that the micro-grid consists of thermal units,renewable energy and a parking lot containing energy storage facilities.This paper proposed an optimization model of energy management considering mobile energy storage characteristics of electric vehicles.The objective function of the model is to minimize the expected total operating costs,including the energy purchase and sales costs in the early stage of the market,the start-up/down costs and power generation costs of the thermal unit,the battery wear and tear costs,and the cost of power exchange with the local power distributor in each scenario.In this paper,Benders decomposition algorithm was utilized to solve the model,and the modified 14-node system was used for simulation verification.The simulation results show that the energy storage characteristics of EV batteries can effectively reduce the total operation cost of the micro-grid.
