This paper investigated the influence of photovoltaic integration on the voltage stability of the 53-Bus distribution grid. Efficiency and quality of voltage in PV system degrades due to instability in voltage in Grid connected system.
Analysis of voltage stability of transmission network with high photovoltaic (PV) integration is a challenging problem because of the stochastic generation of a solar system. Stabilization of the output power is an important criterion for determining the degree of penetration of PV in active distribution networks, considering loading capability.
It can be observed that solar-PV systems improve the voltage stability by enabling more reactive power reserve ( Qs - QL = 615 MVAr) which improves the stability margin ( ( Vo-Vcr )/ Vo ) = 39% of the system in comparison to SGs. Fig. 25 illustrates the reactive power output at the PCC and the terminal voltage of solar-PV systems and SGs.
This paper investigated the impact of large-scale solar-PV generation on long-term voltage stability. A rigorous theoretical analysis was performed with a simple test system to compare the LTVS impact of the solar-PV generation with the SG. Then the Nordic test system was used to conduct a system wide LTVS study with solar-PV generation.
The proposed methodology has been verified by analysing voltage stability of IEEE 14 bus test system, with high penetration of PV energy sources and considering uncertainties associated with load demand. The results provide a clear insight to voltage stability of power grid with different penetration levels of PV energy sources into the power grid.
It shows that every solar photovoltaic generators with transient stability remains connected with the grid without deteriorating with an average fault clearance period of 250 ms. Within the operating range of the solar photovoltaic power plant, such faults should not lead to instability or isolation from the transmission network.
