中文摘要:

直流综合负载接入到直流配电网中必定会影响系统的稳定性，为减轻负载对直流系统的影响，本文提出一种利用储能系统（energy storage system，ESS）对直流配电网中的综合负载进行优化的方法。首先，根据综合负载特性，研究负载和ESS之间的功率协调关系以改善负载特性。其次，在改善负载特性的同时，以ESS投资成本最小为目标对ESS进行优化配置。最后，进行算例分析，结果表明：本文提出的方法可有效改善负载特性，使得直流电压波动得到减少、直流配电网运行稳定性得到明显提高。

英文摘要:

The DC synthetic load is connected to the DC distribution network, which will affect the stability of the system. In order to reduce the impact of load on DC system, in this paper, a method to optimize the synthetic load of DC distribution network by using ESS is proposed. First, based on the synthetic load characteristics, the power coordination relationship between the load and the ESS is studied to improve the load characteristics. Second, while improving the load characteristics, the ESS is optimally configured with the objective of minimum ESS investment cost. Finally, a case study shows that the proposed method in this paper can effectively improve the load characteristics, reduce the DC voltage fluctuations, and improve the stability of the DC distribution network.
