Economic Operation of Microgrid by Considering of Seasonal Effect of Small Hydropower

  • 摘要: 针对小水电集中地区微源运行和小水电、风电的互补特性,考虑小水电发电的季节差异,基于分时电价,以计及微网运行、网际交易、折旧等要素的总成本最低为优化目标,并运用AHP层次分析法建立微网的调度和经济运行模型。通过所建模型优化微源出力,灵活调度蓄水库运行,合理配置主网与微网之间的电能交易。选取典型微网为案例,并根据不同季节的典型负荷曲线进行仿真,结果表明季节特性对于小水电集中地区微网有较大的影响,针对丰水期和枯水期分别制定不同的调度策略是相当必要的;同时也证明了风水互补运行对于提高微网经济性和可靠性都具有重要意义。
    Abstract: As to the features of micro source operation and the complementary relationship between small hydropower and wind power in center area of small hydropower, by taking of seasonal effect of hydropower into account, the minimum operational cost is used as the optimized objective by considering of such factors as micro grid operation, trade, and the depreciation. At the same time, analytic hierarchy process method is used to build dispatching and economic operation model of microgrid, based on which the output of microgrid can be optimized, the operation of storage reservoir is dispatched flexibly, and power trade between main power grid and microgrid can be allocated reasonably by the proposed model. By taking typical microgrid as example, the simulation is carried out according to typical load curves in different season. The results show that the influence of seasonal characteristics on microgrid in center area of small hydropower is large, and it is necessary to formulate different scheduling strategies in wet season and dry season. In other hand, it also can be seen that the complementary between small hydropower and wind power is helpful to improve the economic and reliability of micro grid.
