多园区综合能源系统分区自治式能量合作社区及联合优化调度

Partition Autonomous Energy Cooperation Community and Its Joint Optimal Scheduling for Multi-park Integrated Energy System

多园区综合能源系统具有能源互济互联、协调合作运行、利益主体多元的重要特征,这对各园区间能量交互与协同管理提出了自主自治、隐私安全等要求。为此就多园区综合能源系统能量交易模式及物理实现架构,提出一种分区自治式能量合作社区及优化调度模式。首先针对能量交易模式,引入能源供需比和讨价还价博弈模型,构建合作社区内部交易及其定价机制,模拟能源供需形势及利益分配对社区内部交易的影响,有效激励园区参与合作;其次针对物理实现架构,构建各园区内综合能源系统模型及园区间输送管网模型,建立多园区系统的联合优化调度模型,应用交替方向乘子法分布式求解架构提出了上、下分层的解算方法,实现合作社区能源交互交易,保证园区交易自主、运行自治、信息隐私;最后算例验证了该合作社区与调度模式能够充分挖掘园区互济效益,实现共享收益公平分配,促进园区可持续合作共赢,提升能源利用效率。

The multi Park integrated energy system has the important characteristics of energy interconnection, coordinated and cooperative operation, and multiple stakeholders, which puts forward the requirements of autonomy, privacy and security for the energy interaction and collaborative management among the parks. In this paper, a partition autonomous energy cooperative community and its optimal scheduling mode are proposed for the energy trading mode and physical implementation architecture of the multi-Park integrated energy system. Firstly, aiming at the energy trading mode, by introducing the energy supply-demand ratio and the bargaining game model, this paper constructs the intra-community trading and its pricing mechanism, simulates the impacts of energy supply-demand situations and benefit distribution on the intra-community trading, effectively encouraging the parks to participate in the cooperation;Secondly, according to the physical implementation architecture, the integrated energy system model in each park and the transmission pipe network model between parks are constructed. A joint optimal scheduling model of the multi-park system is established. The alternative direction multiplier method is applied to the distributed solution architecture, and the upper and lower layered solution method is proposed to realize the energy interactive transaction in cooperative communities, ensuring the autonomy of transaction, operation and information privacy in the parks;Finally, an example shows that the cooperative community and dispatching mode can fully tap the mutual benefit of the parks, realize the fair distribution of shared benefits, promote the sustainable cooperation and win-win of the parks, and improve the energy utilization efficiency.
