【摘要】：综合能源配电系统(integrated energy distribution system,IEDS)中能量交互密切,能源耦合关系复杂,储能是其经济与稳定运行的关键环节。传统储能往往费用较高,且网络级大规模储能受限于地理环境、物理状态、经济条件等因素而未能广泛应用。针对上述问题,该文利用电力与天然气的灵活耦合与多能互补特性,通过对IEDS多能流优化调度与网络侧资源综合利用,提出了一种广义多源储能系统(generalized multi-source energy storage,GMSES)模型,可以在不改变IEDS网络结构、不新增储能设备的基础上,实现GMSES网络级储能充、放电功能与能量优化管理。在综合考虑能量流和设备约束的基础上,该文结合具体算例,探究了GMSES能量优化方法,验证了GMSES模型可有效提高系统经济性,并具有平抑可再生能源波动的潜力。
[Abstract]:In the integrated energy distribution system IEDS, the energy interaction is close and the energy coupling relationship is complex. Energy storage is the key link of its economic and stable operation. Traditional energy storage is often expensive, and the network scale energy storage is limited by geographical environment, physical conditions, economic conditions and other factors, and can not be widely used. In order to solve the above problems, a generalized multisource energy storage system generalized multi-source energy storageGMSESs model is proposed by utilizing the flexible coupling and multi-energy complementary characteristics of electric power and natural gas, through the optimal scheduling of IEDS multi-energy flow and the comprehensive utilization of network-side resources. On the basis of not changing IEDS network structure and adding new energy storage equipment, the function and energy optimization management of GMSES network level energy storage charge and discharge can be realized. Based on the comprehensive consideration of energy flow and equipment constraints, this paper explores the GMSES energy optimization method with an example, and verifies that the GMSES model can effectively improve the system economy and has the potential to stabilize the fluctuation of renewable energy.
