基于多代理的主动配电网规划样本自动模拟研究

可再生能源的高渗透率接入、柔性负荷的高参与度、运行协调管理的高效可靠要求,均使得传统的管理投资方式难以满足多主体接入下配电网的投资发展要求。为适应主动配电网中多主体接入,促进清洁能源的消纳,为配电网精确投资规划提供丰富样本,提出基于多代理的主动配电网规划样本自动模拟模型。基于构建的分布式电源、储能及柔性负荷的多代理时序模型,提出了以电网代理引导的主动配电网自动协调模拟策略;考虑负荷增长模式与配电网技术路径更迭,实现不同投资方案下主动配电网的规划样本自动模拟,以提高主动配电网中多主体的利用效率。算例结果表明,所提模型通过追随主动配电网技术路径的发展,能够有效实现配电网长时间尺度的运行模拟。通过自动模拟方法产生的分布式电源出力与负荷波动情况等配电网特征量可用取代作为后续配电网投资规划的数据样本。

Automatic simulation study of planning samples of active distribution network based on multi-agent

With the high increasing penetration of renewable energy, high participation levels of flexible load and high efficiency and reliable operation of coordination management, it is difficult to meet the investment development requirements of distribution network with multi-agent access by traditional way. In order to adapt to the multi-agent access and promote clean energy consumption and provide rich samples for precise investment planning of active distribution network, a model of planning sample automation simulation is proposed based on multi-agent and technical path. According to the built multi-agent models of DG, ESS and flexible loads, an automation coordinated strategy by grid agent guidance is designed. At the same time, in order to improve the utilization efficiency of multi-agent in active distribution network, the model considers load growth and the change of technology path to analyze the economic operation ability under different schemes. The results of the model are verified by following the development of technology path to realize the simulation of long-time scale of active distribution network. The characteristic quantity such as the output of distributed generation and the fluctuation of load generated by automatic simulation method can be substituted as the data sample of the subsequent investment planning of active distribution network.
