提出了一种考虑可靠性准则的微电网储能系统最优规模计算模型。规模较大的ESS在降低微电网运行成本的同时，需要更高的投资成本。提出了使ESS的投资成本和预期运行成本最小的ESS规模优化问题。利用ESS解决了常规机组停运和可再生机组间歇运行造成的发电短缺问题，满足了微电网的可靠性要求。给出了一个实用的ESS模型。利用混合整数规划(MIP)对该问题进行了描述。算例表明了该模型的有效性。
This paper presents a model for calculating the optimal size of an energy storage system (ESS) in a microgrid considering reliability criterion. A larger ESS requires higher investment costs while reduces the microgrid operating cost. The optimal ESS sizing problem is proposed which minimizes the investment cost of the ESS, as well as expected microgrid operating cost. Utilizing the ESS, generation shortage due to outage of conventional units and intermittency of renewable units is handled; hence microgrid reliability criterion is satisfied. A practical model for ESS is utilized. Mixed-integer programming (MIP) is utilized to formulate the problem. Illustrative examples show the efficiency of the proposed model.
