随着风电、光伏等可再生能源大量并入新型电力系统配电网,大量分散的风电、光伏等集群呈现出分布式管理和控制方式,使传统集中式的经济调度方法陷入困境。对此,基于传统一致性算法,文章提出了风电、光伏构成的边缘集群分布式经济调度模型。首先,给出了风电、光伏的边缘集群模型及其波动性特性;其次,推导了传统一致性算法及实现经济调度的优化模型;在此基础上,结合风电和光伏边缘集群模型,提出了风电、光伏的边缘集群的一致性经济调度分布式算法;最后,以某实际系统为例,对所提算法模型进行仿真验证。结果显示了所提模型的有效性。

With the large-scale integration of renewable energy such as wind power and photovoltaics into the new power system distribution network, the traditional centralized economic dispatch method is facing difficulties due to the distributed management and control mode presented by a large number of scattered clusters of wind power and photovoltaics. Based on traditional consistency algorithms, a distributed economic dispatch model for edge clusters composed of wind and photovoltaic power is proposed. Firstly, the edge cluster models of wind and photovoltaic power and their volatility characteristics are presented;Secondly, traditional consistency algorithms and optimization models for implementing economic scheduling were derived;Thirdly, based on this, a consistent economic dispatch distributed algorithm for wind and photovoltaic edge clusters is proposed by combining the wind and photovoltaic edge cluster models;Fourthly, taking a practical system as an example, the proposed algorithm model was simulated and verified, and the results showed the effectiveness of the proposed model.
