摘要: 针对风光储柴微网系统中蓄电池放电深度过大的问题,采用了2层协调调度策略。在第1层柴油发电机与混合储能的协调中,在蓄电池荷电状态达到下限之前,预先启动柴油发电机参与平衡调节;在第2层混合储能的功率分配中,基于蓄电池和超级电容器的动态特性进行功率协调分配。根据上述协调调度策略,建立了风光储柴系统的优化配置模型,采用改进的遗传算法寻求最优配置方案。通过具体算例,验证了所采用的协调调度策略的正确性和有效性。

Abstract: To solve deep battery discharge problem in microgrid constructed by photovoltaic(PV)-Wind-Storage-Diesel system, two layers of coordinated dispatch strategies is presented. In the first layer, diesel generators and hybrid energy storage system are coordinated dispatch with each other. The diesel generators starts before battery state of charge(SOC) reaches lower limit. In the second layer, the power of batteries and super capacitors are distributed based on dynamic characteristics of the hybrid energy storage system. Based on the coordinated dispatch strategies, optimization models of distribution generations (DGs) are constructed and an improved genetic algorithm is applied in optimal dispatch problem. Testing results with example system verifies the correctness and effectiveness of proposed models, algorithm and coordinated dispatch strategies.

Key words: microgrid system, PV-wind-storage-diesel, optimal allocation, coordinated dispatch, genetic algorithm
