Optimization of Power Distribution System with Microgrids Using

Distributed Energy Resources, (DER) such as solar power, wind power, fuel cell, biomass, battery, smart inverters, are becoming more prominent in power distribution systems. TheMicrogrid (MG), a mix of the DER, is a platform which harnesses the potentials locked in these DER. High penetrations of MG sources have greatly impacted the parameters of the power system network. This paper develops indices to optimize voltage stability and loss reduction on the power grid utilizing Microgrid units. The technique used to evaluate the impact of MGs on a distribution power system is the Genetic Algorithm in MATLAB, which determines the optimal placement and size of the MG unit with an emphasis on improving overall integrity of the grid network. The usefulness of the technique is validated on modified IEEE 14 and 57 bus test system.
