Abstract
Abstract
Under the context of building a new type of power system, distributed PV is connected to the distribution network on a large scale, further increasing the penetration rate of the distribution network. The access of distributed PV causes many problems, such as voltage rise at distribution network nodes and transformer power back feeding. This paper first analyses the impact of PV connection at different locations in the distribution on the node voltage of the distribution network. The Grey Wolf Algorithm (GWA) is then applied to optimize the nodal voltage and branch network losses for the rational allocation of PV capacity and access to shunt compensation capacitors. Finally, the method’s effectiveness is verified using the IEEE33 bus system.
