智慧型多層微電網電力調節研究與場域建置(1/2)

The interconnected microgrid system can provide power supply for each other. In this way, the non-planning energy can be regarded as the backup power source and promote the optimization of energy usage. However, most traditional interconnected microgrids implement the control mechanism based on the centralized architecture to collect the data from different microgrid controllers and deliver the control commands after optimization of energy management. Although all the information can be obtained in the centralized architecture, the huge computational and communicational burden would be introduced. Besides, the regulation commands would not be in the real-time manner for the multi-level interconnected microgrid and this would lead to the load shedding or damage. To achieve the optimal power regulation and stability of system operation, thisproject would design a smart multi-level interconnected microgrid based on intelligent control techniques considering the distributed control architecture and operation cost of grid. The key techniques in this project include: (1) power converter design and control with the power sharing function, (2) coordinated control of renewable energy and load shedding strategy for the individual microgrid, (3) energy management andoptimization of operation cost in the microgrid, (4) power control and regulation technique for the interconnected microgrid, (5) optimal energy dispatch and control for the interconnected microgrid, (6) model of fuel cell and dynamic control strategy in the microgrid, and (7) power generation forecasting technique of renewable energy. In terms of system implementation, a 100-kW smart multilevel microgrid demo site is designed and constructed. The demo site can be operated in both grid-connected and islanded mode with 100% renewable energyincluding 70-kW solar power, 35-kW fuel cell, and 110-kWh energy storage system.
