Abstract: This paper presented the allocation of available local distributed energy resources with the aim of maximizing the use of renewable energy resources for Khun Pae Village in Chiang Mai, Thailand, which is considered a microgrid. As a reference, a microgrid simulation was done by HOMER Pro with black box code utilization. This method integrates a new optimal microgrid controller dispatching design using a Modified Heuristic into the existing HOMER scheme to find the minimized Net Present Cost (NPC) and Cost of Energy (COE). The results showed that the NPC and COE based on the Modified Heuristic technique provided lower costs than those obtained from HOMER Pro Load Following. It was also shown that the proposed optimization technique provides smoother and lower operating costs as well as annual throughput to extend battery lifetime.
