Abstract

Power prosumers with rooftop solar panels have risen in recent times. They easily integrate into DC microgrids, due to the nature of their output-DC. Therefore, it is important to study DC prosumer grids. Power management is crucial to the efficient and economic operation of microgrids. In this paper, the power management task of a DC prosumer microgrid is tackled using the Particle Swarm Optimization algorithm in Pyswarm. The task is developed mathematically as a constrained optimization problem with the objective of minimizing the grid's operating cost. The equality constraints of the optimization problem are handled using the Penalty Function approach. Using a six-bus DC microgrid, investigations are carried out on the effect of the penalty parameter on three metrics-objective function value, magnitude of violation and time to reach a solution. Results show that among the penalty parameter values considered for the solution to the power management problem of the six-bus system, and with respect to the three metrics, penalty parameter values le+1 and le+7 are most suitable. Furthermore, studies on the effect of swarm size on the three metrics show that a swarm size between 200 and 250 is ideal.
