| Summary: | A multi-objective cluster classification and voltage control approach for an active distribution network considering resource reserve degree is proposed to solve the problem that the node voltage exceeds the limit after the high penetration rate of distributed photovoltaic (PV) power generation is connected to the distribution network. Firstly, by considering the influence of its own regulation ability on cluster coupling relationship and global control ability when distributed PV power generation is connected, a multi-dimensional cluster classification indicator considering resource reserve degree is established. Then, the K-means clustering algorithm is used to improve the discrete particle swarm optimization (DPSO) algorithm to convert the cluster classification into an optimization solution problem. Then, a voltage control model of the active distribution network cluster is built. With the reactive/active power of the dominant node as the control object, the sequential action and power of distributed PV power generation are determined. Finally, the power grid of a rooftop distributed PV development pilot in a county is taken as a simulation example, and the voltage control effect, system network loss, and PV utilization rate under different schemes are analyzed. The correctness and effectiveness of the voltage control approach proposed in this paper are verified. |
