Current power systems are not designed to support the massive integration of PV and to respond to the grid codes. The application of intelligent and online control methods for better coordination between all parts of modern electrical systems is very important.
Some major standards for PV integration in distribution systems such as IEC 61727, IEEE 1547, and VDE-AR-N4105 are defined and used in to ensure that the power quality and stability defined by grid codes for PV sources connected to the grid are maintained.
In addition, in , to prevent overvoltage problems in power distribution networks, the use of the battery has an important role and three various scenarios for grid conditions, are tested as the voltage control mode, mitigating reverse power flow mode, and scheduling mode.
The PV system candidate nodes have been regarded as 5, 11, 16, 17, 19, 22, 24, 25, 26, 28, 30, and 32, respectively. In scenario 1, the optimal PV system output powers have been determined by considering 0.85, 0.90, 0.95, and 0.99 CLs for UTHD, UIHDh, and URMS in the probabilistic optimization framework.
