中文摘要：
在分时电价及微电网并网运行条件下,为更好地调度储能和可调度型微电源并优化微电网购电及售电功率,建立了计及附加机会收益的冷热电联供(CCHP)型微电网动态调度模型。以一个包含风机、光伏电池、储能、燃料电池、CCHP系统的微电网为例,采用基于模拟退火的粒子群优化算法对调度模型进行动态寻优,从而求得调度周期内各微电源的最佳经济出力,同时比较了CCHP系统相对于分产系统的优势。算例分析验证了所述模型和算法的有效性,仿真结果表明:并网运行条件下,计及附加机会收益的CCHP型微电网调度模型能够在能源梯级利用和节能减排的基础上,优化网内各组成部分的出力从而降低微电网的运行成本。
英文摘要：
In the practice of time-of-use(TOU) electricity price and the microgrid connected to the grid,a dynamic model of combined cooling heating and power(CCHP) type of microgrid considering the additional opportunity income is proposed to better schedule energy storage,schedulable microsources and interactive power from the grid.A microgrid consisting of a wind turbine,photovoltaic,energy storage and CCHP system is chosen to obtain the optimal operation modes of microsources in the scheduling period using the simulated annealing and particle swarm optimization (SimuAPSO) algorithm,and then the advantages of CCHP system with individual systems are compared.The validity of the proposed model and algorithm is proved.Under the condition of microgrid connected to the grid,the dynamic model of CCHP type of microgrid is able to optimize the output of microsources and reduce the costs of the microgrid based on the step utilization of energy and emission-reduction.
