| 摘要: |
| 随着微能源网中风电与光伏占比不断提高，发展多元化的储能技术将会缓解因风光能源波动给能量调度带来的压力。为此，提出将电转氢(P2H)与燃料电池(FC)相结合，作为电热微网的灵活性资源，参与微网的能量调度。在此背景下，构建了包含风电、光伏、P2H、FC、燃气轮机、电锅炉的电热微网日前经济协调调度模型，以微网日运行成本最低为目标函数，综合考虑各设备的出力约束条件，分别分析了P2H与FC在离网运行和并网运行2种模式下对调度所起的作用。采用CPLEX求解器对模型进行求解，算例分析结果验证了所建调度模型的合理性。 |

| Abstract: |
| With the increasing proportion of wind and photovoltaic power in the micro-energy network, the development of diversified energy storage technologies will relieve the pressure of energy scheduling caused by the fluctuations of wind and solar energy. Therefore, it is proposed to combine P2H(Power to Hydrogen) with FC(Fuel Cell) as the flexible resource of electricity-heat microgrid to participate in the energy dispatch of microgrid. Under this background, the day-ahead economic coordination dispatch model of electricity-heat microgrid containing wind power, photovoltaic power, P2H, FC, gas turbine and electric boiler is built. Taking the minimum daily operation cost of microgrid as the objective function, and considering the output constraint of each device, the effects of P2H and FC on dispatch in both off-grid operation mode and grid-connected operation mode are analyzed respectively. CPLEX solver is used to solve the model, and the results of an example show that the proposed dispatch model is reasonable. |
