Sequentially Coordinated and Cooperative Volt/Var Control of PV Inverters in Distribution Networks

Electric distribution grids are seeing an increased penetration of photovoltaic (PV) generation. High PV generation exceeding the grid load demand results in a reverse active power flow grid, which raises voltage level. This paper presents reactive controller to overcome overvoltage problem system. A sequentially coordinated and cooperative volt/var control technique is presented. The proposed aims use as low possible while mitigating issues. Accordingly, it reduces loss associated with probability for curtailment developed each lateral replicated all laterals. coordinates operation smart inverters sequential manner. Cooperative between laterals’ controllers well engaged when individual unable solve their performance evaluated by comparing two other controllers, demonstrates better terms requirement. To conduct simulation study, modified version unbalanced IEEE 13-bus system utilized, includes additional 44 low-voltage bus. study involves simulating 720 operating points across daily time series. indicate that effectively addresses problems occur during periods high
