摘要: |
统的能量路由器能量管理策略未考虑多台设备之间的柔性互联关系,且在港口应用中港机负荷的冲击性和新能源发电的波动性,使区域电网的可靠供电和经济运行面临挑战。为此,基于模糊逻辑控制提出了一种适用于集群式岸电能量路由器的供能精细化就地管控策略。该方法考虑了互联岸电能量路由器之间输出功率的耦合影响,并依据并网模式下可能的功率流向制定了保证电力用户经济效益的模糊控制规则,使储能输出电流根据电池荷电状态(state of charge, SOC)、电网电价以及各台岸电能量路由器净输出功率的变化进行动态调整。该方法计及了互联系统间的协同作用,构建了互联系统间各端口传输功率关系,有利于分布式能源跨台区协同消纳,且不需要上层调度控制,减少了对通信的依赖。仿真结果验证了所提控制策略的有效性和可行性。 |

Abstract: |
Traditional energy management strategies for energy routers do not take into account the flexible interconnection relationship between multiple devices. Also, the shocks of port loads and the fluctuations of new energy generation in port applications make the reliable power supply and economic operation of regional power grids challenging. Therefore, a refined local energy management strategy is proposed based on fuzzy logic control for clustered shore power energy routers. The method considers the effect of coupling of output power between interconnected shore power energy routers. It also formulates fuzzy control rules based on the possible power flow direction in the grid-connected mode to ensure economic benefits for power users. The energy storage output current is dynamically adjusted according to the changes in SOC, electricity price of the grid, and the net output power of each shore power energy router. The method takes into account cooperative interaction between interconnected systems and constructs the transmission power relationship between ports of interconnected systems. It facilitates the synergistic consumption of distributed energy across stations, and does not require upper-level dispatch control, reducing the dependence on communication. The effectiveness and feasibility of the proposed control strategy is verified through simulation. |
