Coordinated Voltage Control Strategy of Distribution Network with Photovoltaic and Hydrogen Energy

The high penetration of distributed photovoltaic (PV) integration and its connection to other forms of energy, such as hydrogen energy, has become an important trend in the development of distribution networks. A coordinated voltage control strategy is proposed, considering OLTC, CBs, PV, ESS, and P2H. In this paper, a comprehensive model for an integrated electricity-thermal-hydrogen energy system is established, and the hydrogen generated by the electrolysis of water is stored in a hydrogen storage tank in order to propel hydrogen-powered vehicles. The objective function considers voltage deviation, network losses, regulation costs, etc. Finally, simulations using the IEEE 33 bus system are performed to validate the effectiveness of the proposed coordinated voltage control strategy.
