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.
distribution network feeders, leading to the improvement of the flexibility and rapidity of the distribution network control. However, drawbacks such as high cost and low utilization rate limit its application. A novel medium voltage photovoltaic power generation device with the SOP function is proposed in this paper.
As shown in (a), P PV = P 1 + P 2. When the PV power generation system is connected to a DN, there are two points of common coupling for the proposed device, and its output power distribution can be optimized according to the voltage levels.
Therefore, the issue of voltage exceeding limits resulting from the connection of distributed PV power generation to DNs can be avoided, leading to further increased network hosting capacity of the distributed PV power generation.
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.
