While, this paper reveals that except for the PV penetration level, the PV imbalance across three phases also has a significant impact on voltage regulation performance, and improper reactive power absorption may lead to worse overvoltage problems in scenarios with unbalanced PV integration.
However, reverse power flow induced by excessive PV power integration will significantly increase system voltage, and the overvoltage problem is becoming the bottleneck for future integration of clean and renewable solar energy resources in distribution systems.
The comparison of Figs. 6 and 7 reveals that, lower but unbalanced PV penetration in distribution systems may lead to more severe voltage regulation problems compared to higher but balanced PV penetration across three phases.
With unbalanced PV power integration, traditional methods without an inter-phase coordination design may cause concerning high voltage on one phase. As a result, PV inverters installed on this phase are exposed to overvoltage problems and disconnection risks.
While in , charging process of electric vehicles is properly scheduled to offset the fluctuations of PV power through a two-stage stochastic optimization algorithm. An innovative concept “prosumer” is proposed in , and prosumers should dispatch either controllable loads (demand response) or storage systems to deal with volatile PV generation.
An interesting phenomenon is that, if PV installation capacities are significantly increased from the current level (48 kWp, 34 kWp, 78 kWp from Phases A to C) to a higher but balanced level (78 kWp, 78 kWp, 78 kWp), either of the decentralized methods can sufficiently compensate the PV power induced voltage rise, as shown in Fig. 7 (a) and (b).
