Abstract

Combined heat and power (CHP) micro-grid combines various distributed generation units, heat supply units, energy storage equipment, electric load, heat load and control devices together to provide users electricity and heat simultaneously. Heat and electricity could be transformed mutually under grid-connected mode and island mode, thus realizing high-efficiency utilization of new energies. However, such new energy unit has higher cost of investment per capacity compared to traditional generator unit. Unreasonable power capacity of micro-grid will cause not only wastes of wind energies and electric energies, but also over high cost of investment. Therefore, it is of important significance to plan capacities of units in CHP micro-grid reasonably according to local weather, wind speed and load. In this paper, a model for optimizing capacity assignment of CHP micro-grid with heat pumps was established. Targeting at normal operation of CHP micro-grid and optimum economical efficiency, this model combines historical meteorological data of regions to distribute capacities to wind turbines, CHP unit, lead-acid battery and the heat pump reasonably for warm and cold seasons respectively
