| Abstract: | With the increasing connection of controllable devices to isolated community microgrid, an economic
operation model of isolated community microgrid based on the temperature regulation characteristics of
temperature controlling devices composed of wind turbine, micro-gas turbine, energy storage battery and
heat pump is proposed. With full consideration of various economic costs, including fuel cost, start-stop
cost, energy storage battery depletion expense and penalty for wind curtailment, the model is solved by
hybrid particle swarm optimization (HPSO) algorithm. The optimal output of the micro-sources and total
operating cost of the system in the scheduling cycle are also obtained. The case study demonstrates that
temperature adjustment of temperature controlling devices can adjust the power load indirectly and
increase the schedulability of the isolated community microgrid, and reduce the operating cost of the
microgrid. |
