Evaluation of Distributed Photovoltaic Consumption Capacity of Distribution Network Based on Cuckoo Search Algorithm

Accessing distributed photovoltaic (PV) in distribution network will bring many adverse effects. It is very important to study the consumption capacity of distributed PV in distribution network for maintaining the safe operation of distribution network. In this paper, the impact of distributed PV power access on power quality, short-circuit capacity and network loss of distribution network is studied by establishing an optimization model aiming at maximizing the net benefit of photovoltaic accessed. A cuckoo algorithm for solving the problem of PV consumption is proposed. In the actual distribution network model, the economic benefits of PV accessed are analyzed from the aspects of power factor, load level and PV investment coefficient, respectively. The availability of the consumption capacity analysis method proposed in this paper is verified.
