Wind/PV/Battery micro-grid hybrid simulation research on operation control based on RTDS and controller

Wind/PV/Battery micro-grid hybrid simulation research on operational control is an important link in the development of renewable energy power generation technology. This paper establishes a model of micro power unit control system based on RTDS and a digital physical hybrid simulation model of micro power unit control system based on RTDS and controller, constructs a Wind/PV/Battery micro-grid experimental platform, and its electrical topology structure, system structure and communication architecture are given. In this paper, switching and operational control strategy of micro-grid are proposed, and through experiment to verify. This paper first verifies the feasibility of the digital physical hybrid simulation, and then designs a variety of conditions for simulation of grid-connected/islanded mode switching. The results show that micro grid experimental platform can be in a state of equilibrium under different conditions and keep running smoothly during the adjustment process, the effectiveness of the proposed control strategy is verified. Through research and construction of this platform, the performance of the control strategy can be tested and debugged on the physical platform, and the control parameters can be modified in real time, at the same time, it provides important practical basis for practical engineering design.
