Distributed generation (DG) and microgrid will play important roles in the future electric network operations. They could improve energy efficiency, minimize environmental impacts and enhance power system reliability. A power scheduling approach considering load/generation changes and time of use (TOU) tariff for a low voltage DC microgrid incorporating energy storage battery, fuel cell and photovoltaic power generations, is presented in this paper. The problem is solved by a multi path dynamic programming (MPDP) approach. Simulation results illustrate the benefits of DG and energy storage integrations in reducing electricity bill for customers adopting DC distribution system.
