基于不同类型负荷和分布式电源的时序特性以及不同类型分布式电源的环保性能,建立考虑环境成本的微网分布式电源选址定容规划模型,以分布式电源投资费用、燃料费用、网络损耗费用和环境赔偿费用最小为目标函数,采用基于蒙特卡罗模拟的随机潮流计算方法判断规划方案是否满足潮流约束及计算网络损耗.最后采用遗传算法对规划模型进行求解.算例结果验证了模型的合理性.

@@@@ Based on timing characteristics of differnet types of loads and distributed generations (DG) as well as environmental perfomances of different types of DG, a planning model for optimal site selection and capacity determination of DG in microgrid, in which environemental cost is taken into account, is built. In the built planning model, the minimization of annual cost of microgrid, including the investment cost for DG, the fuel cost, the cost of network loss and the environment compensation cost, is taken as objective function, and the stochastic power flow based on Monte Carlo simulation is adopted to judge whether the built planning model can meet power flow constraint or not and to calculate the network loss. Finally, the built planning model is solved by genetic algorithm. The reasonableness of the built model is verified by planning results of a 34-bus microgrid system.
