摘要
双碳目标下为提高园区供能的清洁性和经济性,提出基于风光发电的多园区共享氢储能容量规划方法。首先,利用风、光发电与多园区用户用能的时空互补特性,建立多园区共享氢储能实现清洁发电、经济供能的基本框架,以实现氢储能的容量和能量共享。其次,兼顾多园区的利益诉求,提出基于合作博弈的共享氢储能容量配置模型与投资成本分摊方法,以合理配置各设备容量、提高氢储能的投资经济性。最后利用算例验证所提多园区共建共享氢储能系统的优化配置模型与投资成本分摊方法的可行性与竞争性。结果表明,多园区共享模式较自配模式分别降低投资与碳排放成本26.4%与17.4%,氢储能可更灵活地实现集中式储能资源的共享使用,尤其对具有间断性发电特征的用户优势明显。
To improve the cleanness and economy of energy supply in the park under the dual-carbon target,a planning strategy of shared hydrogen energy storage capacity in multiple parks based on wind power generation is proposed.Firstly,the basic framework of multiple parks sharing hydrogen energy storage to realize clean power generation and economic energy supply is proposed.The time-space reuse of hydrogen energy storage is realized by using the space-time complementary characteristics of wind and PV generation and multi-microgrid user energy consumption.On this basis,the interest demands of multiple independent microgrids are taken into consideration,and a shared hydrogen energy storage capacity allocation model and investment cost allocation method based on a cooperative game are proposed to reasonably allocate the capacity of each equipment and improve the investment economy and flexibility of hydrogen energy storage system.Finally,a simulation example is given to verify the feasibility of the proposed optimal configuration model and investment cost allocation method for jointly constructing and sharing hydrogen energy storage.The results show that the multi-parks sharing reduces the investment and carbon emission costs by 26.4%and 17.4%compared with the self-allocation mode.Hydrogen energy storage can realize the sharing use of centralized energy storage resources more flexibly,especially for users with intermittent power generation characteristics.
