摘要:
      根据并网型交直流混合微网的结构及运行要求提出4层运行方式。为了反映储能损耗的非线性特性,提出一种储能损耗成本积分计算模型,并以设备维护成本、储能及换流损耗成本和购售电费构成的日运行费用最小为目标,建立了交直流混合微网经济优化模型。实际算例分析表明经济参数之间的耦合关系决定交直流微网的运行方式,分析结果验证了所提并网型交直流混合微网运行方式、经济优化模型及储能损耗积分模型的合理性。
Abstract:
      According to the structural and operational requirements of a grid-connected AC/DC hybrid microgrid, four levels of operational modes are proposed. In order to reflect the nonlinear characteristics of energy storage loss, an integral calculation model for energy storage loss cost is proposed. The minimization of daily operational cost is taken as the objective function, which consists of the cost of equipment maintenance, energy storage loss, converter loss, and electricity purchasing and selling cost. And the economic optimization model of the AC/DC hybrid microgrid is developed. The results of actual examples show that the coupling relationship between economic parameters determines the operational modes of AC/DC hybrid microgrid. The analysis results verify the rationality of the proposed operational modes of AC/DC hybrid microgrid, economic optimization model and energy storage loss integration model.
