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.
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.
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.
Moreover, from the observation of the results displayed in Table 5, it can be confirmed that when DR is implemented, photovoltaic system 1 (PPV1) supplies more power to the distribution system between 11:00 and 14:00 as compared to the scenario without demand response.
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 distributed voltage control, the distribution network with EVs and PVs connected is first partitioned into several regions based on the similarity of bus voltage sensitivity. Then, regional voltage control is applied to each regional distribution network via the active and reactive power control of their member EVs and PVs [34, 35].
