Integration of PV Distributed Generators into Electrical Networks for Investment and Energy Purchase Costs Reduction by Using a Discrete–Continuous Parallel PSO

The problem of optimally integrating PV DGs into electrical networks to reduce annual costs (which include energy purchase and investment costs) was addressed in this research by presenting a new solution methodology. For such purpose, we used Discrete–Continuous Parallel Particle Swarm Optimization method (DCPPSO), which considers both the discrete continuous variables associated with location sizing an network employs parallel processing tool times. optimization parameters proposed methodology were tuned using external algorithm. To validate performance DCPPSO, employed 33- 69-bus test systems compared it five other methods: BONMIN solver General Algebraic Modeling System (GAMS) four discrete–continuous methodologies that have been recently proposed. According findings, DCPPSO produced best results terms quality solution, time, repeatability any size, since showed better as size system increased.
