The intermittency problem of solar PV, typically in the range of minutes, will become very significant in Singapore as the installations of PV systems continue to increase. Conventionally, large energy storage systems are deployed as an energy buffer to compensate for the deficit or surplus of power supplied by solar PV systems.
Conclusion This paper has proposed a demand response management (DRM) algorithm for overcoming solar PV intermittency. The DRM algorithm will enable building operators to manage solar PV intermittency locally at the building level and thus reduce its impact on the grid stability and reliability.
Understanding the nature of this intermittency is important to make informed decisions regarding solar power plants, size and location, transmission and distribution systems planning, as well as thermal generation units and electricity markets operations.
Uncertainty of distributed photovoltaic (PV) power brings great challenges to the safe and stable operation of power system, in which the intermittency problem is more challenging than the fluctuation.
The intermittency of distributed PV power is one of the intrinsic properties of uncertainty, which cannot be neglected due to its strong contribution to the phenomenon of sudden variations in distributed PV power, especially in the presence of severe cloud phenomena [ 12 ].
Our results highlight how reliability analysis must account simultaneously for the mean and intermittency of solar inputs when assessing the impacts of climate change on photovoltaics. The intermittency of solar resources is one of the primary challenges for the large-scale integration of the renewable energy.
