基于风电消纳的多类型储能系统联合经济调度

为使电力系统尽可能提高风电接纳能力,建立了基于风电消纳的实时失调成本模型,考虑到安全性、环保性,分别构建了基于风电-火电调度总成本模型和基于风电-火电-联合储能系统调度总成本模型,并采用HS-PSO混合算法求解调度总成本模型。算例仿真结果表明,抽水蓄能电站、蓄电池和超级电容器混合储能系统在增加经济效益、提高风电接纳能力方面优势明显;同时验证了储能系统容量与弃风率的关系,为含风电并网运行的系统经济调度提供了依据。

Joint Economic Dispatching of Multi-type Energy Storage Systems Based on Wind Power Consumption

In order to make the power system increase the wind power acceptance capacity as much as possible, the paper establishes the real-time offset cost of wind power consumption. Considering safety and environmental protection, a total cost model based wind power-thermal power dispatching and a total cost model based wind power-thermal power-joint energy storage system were established. The hybrid HS-PSO algorithm was used to solve the total cost dispatching model. The simulation of the example shows the advantages of the pumped storage power station, battery and super-capacitor hybrid energy storage system in increasing economic benefits and improving wind power acceptance. It also verifies the relationship between the capacity of multi-type energy storage system and the abandonment rate, which provides a basis for economic dispatch of the system with wind power grid-connected operation.
