Cuckoos-Search Based Hosting Capacity Calculation for Distributed Grid-Connected Photovoltaic Generation Considering Economic Cost

With the rapid development of photovoltaic (PV) industry, the access scale and mode of distributed PV system will directly affects the PV development strategy as well as the planning, expansion and reconstruction of distribution system. The optimization model is given in which the objective is the maximum of net profit for PVs' access. Cuckoos Search (CS) algorithm is proposed as the optimization algorithm. The economic benefits of PVs' access are analyzed in the IEEE standard examples from the points of installation location, load type of access point and cost coefficient of distributed PV. Finally, the access principle is proposed to ensure the maximum net benefits of distributed PV. The IEEE standard examples show that the model given in this paper can effectively calculate the maximum acceptable capacity considering the benefit and cost of distributed PV.
