提出利用微能源网内部相对容量较大的微型燃气轮机调峰,通过优化调度微型燃气轮机的电、热出力,实现接入微能源网的光伏出力的等效平滑,增加光伏消纳.调节策略以微能源网系统日运行费用最小为目标函数,建立该微能源网经济调度模型,使用混合整数非线性规划算法求解.算例计算表明:1)基于微能源网内部微型燃气轮机10％装机容量/min的调峰速度,可获得76％装机容量的电力调峰深度,26.7％装机容量的热力调峰深度,实现光伏电源波动性出力的等效平滑.2)在微能源网日运行周期内,光伏电源出力离散系数比等效平滑前降低65.18％,光伏电源出力得到等效平滑,使得光伏电源出力消纳平均提高4.86％;3)与以热定电和以电定热2种调度策略相比较,使用本文提出的调度策略可使系统日运行费用分别降低7.323％和10.472％,表明所提模型和调度方案的经济可行性.,This paper proposes that using intal larger capacity of micro turbine to adjust the fluctuations of photovoltaic power through optimizing the electricity and heat output of the micro turbine,which can effectively improve the consumption of photovoltaic generation.Micro-grid minimum operating cost is seen as optimization goal,and an economic optimal dispatching model is presented.Then,the model is solved using the mixed-integer no linear programming method.Results showed that micro turbine’s obtains 76％ of rated capacity in electricity peaking depth and 26.7％ of rated capacity in heating power peaking depth based on its peaking speed of 10％ installed capacity pear minute,which is beneficial to smooth the output power of photovoltaic.Second,photovoltaic power consumption average increases by 4.86％,because it’s coefficient variation of power generation is reduced by 65.18％ than before and the equivalent output of intermittence photovoltaic power generation has been equivalent smoothed.Last,The system operates under three different scheduling strategies,tning out the optimization scheduling strategy in this paper can make the system daily operating cost reduced by 7.32％ and 10.47％ than following the thermal load and following the electric load operation strategy,the economic feasibility of the proposed model and optimal dispatching strategy is verified.
