Capacity Optimization Configuration Of Distributed Power In Microgrid

In face of the dual pressure of global environmental pollution and energy crisis,various countries in the world focus on clean renewable energy without no pollution including solar energy, wind power and so on. Regarded as a new way of organization of energy, Microgrids provide people a new perspective of sustainable development of energy as well as resolve the problem of large-scale connection of solar energy. This thesis aims to research energy management, optimal scheduling and distributable control in microgrids, summarizes and absorbs researching achievements at home and abroad, constructs microgrids’ energy-management-optimal-scheduling model,proposes two control strategy of inverter power source of high performance.At first, on the basis of generation principle and scheduling characteristic of various distributable generation, constructs mathematical models of photovoltaic generationwind power, fuel cell, micro-gas-turbine and energy storage.Secondly, on the consideration of distributable units’ costs of fuels, pollution fines, maintenance, energy of interaction with large power grid, constructs microgrids’ energy management optimal scheduling mathematical model, determines four strategies of energy management. Then, introduces concepts and features of standard particle swarm algorithm, makes improvements directing at its shortages.Validate the effectives of the model proposed in this thesis and analyze results of every strateg’s model.
