Solar photovoltaic (PV) systems will drive deep electrification of energy systems leading to clean energy 2050. However, connecting large amounts of solar PV systems on direct current (DC) networks, like solar farms and potential future DC distribution systems, would lead to over voltages and loss of solar PV power output due to voltage issues.
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.
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.
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.
Abstract: Large solar photovoltaic (PV) penetration using inverters in low-voltage (LV) distribution networks may pose several challenges, such as reverse power flow and voltage rise situations. These challenges will eventually force grid operators to carry out grid reinforcement to ensure continued safe and reliable operations.
For distribution networks with increasing PV integration, a local voltage regulation approach is suggested in . A very short-term solar generation forecast, a medium intelligent PV inverter, and a reduction of the AP are reported as forecast techniques.
