Design And Development Of Platform Independent Microgrid System Optimization Software

In the island or remote areas will be distributed generation units of various types together toform independent microgrid system, can effectively play the advantages of a single energy systems,to achieve a variety of complementary energy sources, improve the independent microgrid systemefficiency and energy utilization rate, compared to the single optical storage systems or air storagesystem with lower cost and power supply high reliability, is one of the effective means to solve theremote areas and islands of power supply.The optimization design system of independent microgrid is independent of network micro coretechnology system, it includes consideration of distributed power load forecasting, the micro gridstructure, aspects of micro source optimization and planning the final evaluation. At present, thereare many mature field of planning and design of network planning software used in microgrid. Thesoftware to improve the design level of planning power grid, played a significant role in reducing theplanning staff labor intensity. Among them, HOMER and Hybird2for the optimization design of thesimulation software of representative. However, they have some shortcomings.Capacity allocation problem in this thesis include diesel generator, wind power, photovoltaic andlead-acid battery stand-alone microgrid system, which included the multi-objective optimizationdesign model of microgrid in whole life cycle of the present value of the total cost of the loss rate,load capacity and pollutant emission. The optimization model of the control strategy, considering thecombination of several diesel generator start-up mode, energy storage coordinated control strategybetween batteries and diesel generators, as well as the system reserve capacity etc.. In theoptimization variables, select the device type and installed capacity at the same time design. Designand development of the independent visualization based on independent micro network optimalplanning model of the micro network planning software. Its main function modules include: thenetwork equipment management, the microgrid load forecasting, microgrid energy management,network optimization planning, comprehensive assessment of network planning, the function of eachmodule are described in detail. Finally, the independent micro network planning software developedby ourselves, for an independent Island microgrid system carried out research on the optimizingscheme of distributed generation units and storage of different control strategies in different targetcombination, the battery.
