In addition, the voltage fluctuation and power quality issues may limit the PV penetration level and hence mitigation measures are needed to alleviate the potential problems. In this paper, the impact of PV on the distribution network in term of voltage performance and losses has been investigated by using the OpenDss simulator tool.
Photovoltaic (PV) technology is rapidly developing for grid-tied applications around the globe. However, the high-level PV integration in the distribution networks is tailed with technical challenges. Some technical challenges concern the stability issues associated with intensive PV penetration into the power system are reviewed in this study.
The severity of these issues depends on the penetration level of PV, configuration of distribution system and the location of PV in distribution system. In such cases, high level of PV penetration can inject power to transmission network which can affect the voltage level and protection setting of the distribution system.
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.
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.
