中文摘要:

能源枢纽是多能源综合利用的主体单元，具有多能互补的优势。本文首先对基本的能源枢纽进行拓展，建立了包含风电、多种储能以及电转气(power-to-gas, P2G)设备的能源枢纽模型，并将用户侧的电、气、热等多种柔性负荷纳入需求侧响应资源。在此基础之上，考虑分时电价与分时气价，构建能源枢纽的多目标日前综合优化调度模型，并采用法线边界交叉(normal boundary intersection, NBI)法进行求解。最后，算例在四种不同的能源枢纽运行场景下进行测试，结果表明：P2G、储能以及柔性负荷参与调度，不仅能提高能源枢纽消纳风电的能力，还能降低经济成本和减小碳排放。

英文摘要:

Energy hub is a unit that can achieve the integrated utilization of multi-energy and has the merit of complementarity. Firstly, basic energy hub is developed and a model is established which includes wind power, power-to-gas and energy storage, and then many kinds of flexible load are considered as the demand-response resources, including electricity, gas and heat. After that, a multi-objective comprehensive optimal dispatch model of the energy hub is established considering time-of-use price of electricity and gas, and normal boundary intersection (NBI) method is applied to solve the problem. Finally, a case study of energy hub is carried in four different scenarios. Simulation results show that P2G device, energy storage and the participation of flexible load are able to increase the utilization of wind power and decrease the cost and carbon emission of the energy hub.
