Active-Reactive Power Coordination Optimization in Distribution Network Interconnected with Photovoltaic-Hydrogen-Energy Storage Systems
The access of a photovoltaic power station with a hydrogen energy storage system (HESS) to the distribution network can increase the proportion of photovoltaic consumption, reduce the distribution network losses, enrich the types of renewable energy, and improve economic efficiency. Therefore, an active-reactive power coordination control strategy considering hydrogen storage energy and reactive power control of grid-connected inverters is proposed. Considering the uncertainty of photovoltaic output, the active-reactive optimization model of the distribution network is constructed which contains the HESS in response to the time-of-use price, the reactive power of the inverter, the tap adjustment of the on-load transformer and the switching of the shunt capacitors. And a new HESS multistage start-stop control strategy is also proposed. Taking the largest PV consumption, the maximum operating revenue of hydrogen storage and distribution network as the optimization goal, the DICOPT solver of commercial planning software GAMS are used to solve the problem. The improved IEEE33 node system is used to analyze the effectiveness of the proposed model and coordinated control strategy.
