  We present a heuristic search method for distrubuted energy resource sizing,
released in Microgrid Planner, an open-source software platform. Our method is
constructed to identify a wide range of microgrid design options that satisfy a
given set of power load requirements, allowing a decision maker to weigh
trade-offs between potential designs and select preferred solutions. We
introduce a global binary search algorithm to build a diverse set of microgrid
design options and refine them using a local linear search method.
