PV Hosting Capacity Calculation Using Particle Swarm Optimization

In recent years, the utilization of renewable energy sources (RES) such as photovoltaic (PV) is wide. To keep following the vast development in RES technology, it is important to evaluate the capability of the existing power distribution systems to accommodate the penetration of RESs and estimate their hosting capacity (HC). This paper proposes a methodology to calculate the maximum photovoltaic hosting capacity (PVHC) for any existing radial power distribution system. The proposed methodology can solve an optimization problem using particle swarm optimization (PSO) technique. A decoupled linear power flow model (D LPF) is used in the proposed methodology to ensure fast computation. The location of installed PV in existing power systems is not fixed and depends on many factors. Sometimes, the location of installed PV is not known. Other cases require installing PV in a specific bus/busses. Therfore, two approaches are proposed to cover as many cases as possible and calculate the maximum PVHC for various cases.
