In this two-part review, the implications of high PV penetration on the stability and reliability of power systems are comprehensively assessed. This paper, the first of the two, reviews the impacts of PV on the power systems' voltage, frequency, protection, harmonics, rotor angle stability, and flexibility requirement in detail.
The high PV penetration can have serious implications on the stability and reliability of power systems. In this paper – the first part of a two-part review – the characteristics of PV systems that bring challenges for power system integration have been identified.
Nevertheless, depending on the inverter protection mechanism, the fault current profile of a distribution system with high PV penetration can be very different from that without PV (Hooshyar et al., 2013), which might warrant a change in the relay and protection setting of the system.
To mitigate the voltage disturbances in a system with massive PVs integration, some techniques are devoted such as frequency regulation techniques, active power curtailment, reactive power injection (RPI), and storage energy. Also, with a high penetration level of distributed generators, the potential of dynamic grid support is discussed.
By analysing maximum PV penetration in 16 feeders representative of the U.S radial distribution feeders, Hoke et al. (2013) found that, in general, evenly distributed PV cause the least voltage problems and that the closer the PV is to the larger grid (as opposed to the end of the feeder), the better in terms of overvoltage problems.
When the rated capacity of the connected distributed photovoltaic is equal, the short-circuit capacity ratio is small, and the short-circuit capacity of the grid-connected point is large, indicating that the electrical distance between the node and the system power supply is small and the connection is close.
