| description | Aiming at the voltage violation problem caused by distributed photovoltaic connected to the distribution network, a distributed voltage control strategy based on consistency algorithm is proposed considering the economy of voltage regulation of battery energy storage and photovoltaic inverters. Firstly, the voltage regulation mechanism of photovoltaic inverter and energy storage is analyzed, and the voltage sensitivity parameters of distribution network which can be used for distributed iterative calculation are deduced. Secondly, life loss models for energy storage batteries and photovoltaic inverters are established separately. These models are employed to derive unit power cost models. Unit voltage regulation cost models are then constructed by combining the voltage sensitivity parameter. Finally, with the unit voltage regulation cost as the consistency variable, a distributed voltage control strategy based on the consistency algorithm is designed, resulting in power regulation schemes for each node's energy storage and photovoltaic inverter. The simulation results demonstrate that the proposed control strategy can consider the lifetime loss of each node equipment and the overall voltage regulation economy, and fully reduce the voltage control cost of distribution network on the premise of effectively inhibiting voltage violation. |
