The comprehensive analysis of the results indicates that, with the aid of demand response, the suggested distribution system planning and operating models optimize the integration of photovoltaic systems by maximizing the hosting capacity while minimizing the network losses and the voltage deviation for the benefits of both utilities and consumers.
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.
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.
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.
Both with or without demand response implementation, the solar PV capacity had increased to cater exclusively for the load demand between 11:00 and 14:00 h, period during which grid demand is null.
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.
