Research on Day-ahead Dispatching Strategy for Grids With Shared Electric Vessels on Pelagic Islands

针对远洋海岛呈现源荷空间逆向分布的特征,提出一种计及共享全电船舶(shared electric vessel,SEV)参与的海岛电网日前调度策略。首先,提出SEV概念,利用电动旅游班船的闲置储能的共享化,实现岛际能量的转移。进而,根据SEV的时空转移特性,建立了精确的SEV模型。在此基础上,以系统运行成本最小为目标,构建了计及SEV参与的海岛电网日前调度模型,并通过Shapley值法对运营利益在SEV方和海岛电网方进行合理分配。仿真结果表明,基于SEV的远洋海岛能量供给系统在兼顾客运需求的同时实现灵活的新能源消纳和负荷支撑,通过"共享"实现"双赢"。

Considering the characteristics of the reverse space distribution for source-load on pelagic islands, this paper proposed a day-ahead dispatching strategy for the power grid on islands that takes into account the participation of shared electric vessel(SEV). First of all, the concept of SEV was proposed to realize the transfer of inter-island energy by sharing the idle energy storage of electric travel ships. Furthermore, based on the time-space transfer characteristics of the SEV, an accurate SEV model was established. On this basis, aiming at minimizing operating cost of the system, a day-ahead dispatching model of the power grid on islands, which takes into account the participation of SEV, was constructed, and the operational profits were rationally distributed between the SEV and the power grid on islands by the Shapley value method. The simulation results show that the SEV-based energy supply system on pelagic island realizes flexible consumption of new energy and support of load while meeting the passenger demand, and the system also realizes "win-win" by "sharing".
