Abstract
The Total distribution system losses of PT PLN ULP Purworejo reach 10.467%as technical and non-technical losses which were very high compare to the maximum limit (5%). In this research, Photovoltaics (PV) Distributed Generation (DG) was installed as an active power injection to reduce the system’s losses. This research determined the hosting capacity of PV including the location and capacity of the PV. The problem was modeled into an optimization problem and was simulated using Particle Swarm Optimization (PSO) algorithm in MATLAB environment. The simulation was considered the voltage, power factor (pf), and branch current as constraints. The simulation was conducted on the existing system of Feeder 7 of PT PLN ULP Purworejo distribution system. Backward Forward Sweep (BFS) method was used for load flow analysis. As the load flow analysis result, the technical losses on a feeder 7 reach 2.676% of feeder 7 supply. The simulation results showed that by installing optimal distributed PV, the technical losses in feeder 7 were reduced to 1.351%. The overall losses of PT PLN ULP Purworejo become 10.045%.Keywords
