摘要:

为了降低微网并网时的运行成本,同时协助电网"削峰填谷",提出一种考虑负荷中断的微网并网经济调度模型。模型以微网为中间环节,构建一种新型负荷中断补偿机制,同时引入浮动补偿电价,该电价受到中断功率与中断时间的影响,可以反映用户满意度的变化。以一个包含风力发电机、光伏电池、微型燃气轮机、燃料电池、蓄电池以及可中断负荷的典型微网为例,通过Cuckoo-Search算法求解模型,给出最优中断组合、调度结果和运行成本,并求出极限中断电量。结果表明,该文模型与算法可行,可以为各参与方创造可观的经济效益。

Abstract:

To reduce the operation cost of grid-connected microgrid and give assistance to load shifting in power grid, this paper proposes an economic dispatch model of grid-connected microgrid with considering load interruption. The model regards microgrid as an intermediate link and establishes a new load interruption compensation mechanism. Floating compensation price is introduced to reflect user satisfaction, which is affected by interrupting power and time. We select a typical microgrid consisting of wind turbines, photovoltaic cells, micro turbines, fuel cells, storage battery and interruptible load as example, adopt Cuckoo-Search algorithm to solve the model, obtain the optimal interrupting combination, dispatch result and operation cost, as well as the limit interrupting energy. The results show that the model and algorithm are feasible and can create remarkable economic revenue for all participants.

Key words:  microgrid, economic dispatch, compensation mechanism, floating compensation price, Cuckoo-Search algorithm
