Quantification of wind curtailment on a medium-sized power system and mitigation using municipal water pumping load

Abstract

The issues of climate change and dependence on fuel imports as well as a good local wind resource have led to a significant expansion of wind generation on the power system of Ireland in recent years, with further development planned. As it operates on a relatively small and isolated system, Irish wind generation must be carefully managed to mitigate its variable nature. This could lead to significant curtailment of wind power for system stability reasons, undermining the economic case for wind generation and reducing its effectiveness at displacing traditional, fossil-fired generation.This work quantifies the potential curtailment that might be seen on the future Irish and other power systems under several different scenarios, and presents Demand Side Management (DSM) as a tool to reduce curtailment. DSM of a water supply system is investigated to this end, as well as the inputs that would be necessary for such a system in order to benefit both the water system operator and the power system as a whole.

Guiding urban water management towards 1.5 °C

“…Specifically, the operation of pumps, pressure valves, and storage tanks can be deferred for short periods or initiated earlier than planned to modulate electricity usage in response to realtime prices or requests from the electricity system operator 43,44 . These real-time requests help manage the variability from loads and generation on the grid 45 . Supplying these services with urban water systems avoids the development of dedicated energy storage infrastructure.…”

Integration of Electric Vehicles into Microgrids: Policy Implication for the Industrial Application of Carbon Neutralisation in China

“…In the past decade, the power industry has actively promoted energy conservation and emission reduction. However, due to economic costs and load constraints, wind and solar curtailment persists [3][4][5][6]. With recent policy incentives, carbon neutralisation and the vigorous development of electric vehicles and renewable energies have become inevitable trends in the power industry [7][8][9].…”

The Use of Machine Learning and Performance Concept to Monitor and Predict Wind Power Output

“…With that in mind, improving wind power output prediction has become important not only in its design, but also in its operational phase. A better understanding of production fluctuations could be beneficial to operators in order to minimize curtailment losses [2], plan maintenance in better periods, considering lower wind regimes [3], or even assist them to identify abnormalities in the equipment [4], [5]. All this together, could support operators to increase the overall production as well as evaluate more precisely the real efficiency of the wind farm.…”
