Is the voltage of rural solar power generation stable

Three static techniques (i.e. Power flow, Continuation Power Flow (CPF) and the Q–V curve) are used to assess the voltage stability of the power grid with a Solar Photovoltaic Generator.

The stochastic nature of solar generation and the load demand can greatly affect the grid voltage stability. In order to study the grid voltage stability, considering the intermittent nature of solar generation and the uncertainty in load demand, a framework using Monte-Carlo simulation is proposed in this section.

This paper emphasize voltage stability issues in grid interconnection to solar PV system. It also discusses concept of voltage collapse and stability thoroughly along with mitigation technique for generation, transmission and distribution system.

Maintaining acceptable voltage levels at all points along a distribution feeder is a fundamental operating requirement of all electric distribution utilities, large or small, rural or urban. Fluctuat - ing power generation from distributed PV can impact the operation of any voltage regulation.

These ramp rates may lead to power quality problems, such as voltage fluctuations, in the low-voltage (LV) electricity grid. This paper firstly assesses the impact of a growing number of distributed PV systems on the voltage profile in a LV grid by considering PV penetration rates of 40%, 70% and 100% of the local rooftop capacity.
