Analysis of Distributed Photovoltaic Grid Connection Acceptance Capacity Considering Joint Benefits

In response to the safety and economic impact of large-scale distributed photovoltaic grid connections on the distribution network, this paper proposes a distributed photovoltaic grid connection acceptance capacity model that maximizes the joint benefits of photovoltaic power plants and the distribution network while taking into account the constraints of grid-safe operation. Firstly, a brief description of the influence of distributed photovoltaic access on the distribution network was provided, followed by the presentation of a multi-objective optimization process for photovoltaic access to the distribution network. Then, taking into account electrical deviation, system loss, investment cost, and photovoltaic consumption ratio, a combined target distributed photovoltaic acceptance capability model was developed. Furthermore, the SSA sparrow search method was used to maximize the ideal position and maximum capacity of distributed photovoltaic access. Finally, the model's effectiveness was demonstrated by using distributed photovoltaic integration into the IEEE 33 node distribution network as an example, and the photovoltaic acceptance capacity at maximum joint benefit was obtained.
