On the management of wind power intermittency

Abstract

Nowadays, the world is encountering severe challenges in the energy generation sector. Environmental issues like climate change, global warming and Green House Gases (GHGs) and also social issues like dramatic increase in global population and increasing energy demand are the main causes of global concerns about energy resource management. In this regard, Renewable Energy Sources (RESs) are the suitable substitution to replace the conventional generating units that emit GHGs due to the use of fossil fuels. Among all RESs, wind energy seems to be promising for generating emission-free electrical energy. However, it is naturally unpredictable due to its intermittency which leads to s ome technical problems such as generation imbalance as well as optimal reserve allocation. This paper investigates the solutions to compensate wind intermittency through introducing various technolo gies such as Pumped-Hydro Storage (PH S) units, Plug-in Hybrid Electric Vehicles (PHEVs), solar energy and other electric storages like batteries.

Overview of insular power systems under increasing penetration of renewable energy sources: Opportunities and challenges

“…Also, to balance the lack of production during some periods, generation adequacy has to be reserved, leading the power system to a vulnerable state, especially in non-interconnected islands. Nevertheless, intermittency management is performed using sophisticated tools and wind can be considered a reliable source of energy in long-run [45]. Another concern that is associated with the operation of wind-farms and can be significantly important for small islands is the noise pollution near the wind park.…”

“…Apart from the aforementioned solutions, demand-side and electrical energy storage [64,65] technologies offer a great opportunity for increasing the flexibility of insular power systems. Flexibility will enable a most efficient utilization of the RES production that in an inflexible power system may be curtailed to maintain the generation-demand balance (or to avoid congesting transmission lines) and thus decreasing the environmental and economic potential of wind power production.…”

Synoptic and sub-synoptic circulation effects on wind resource variability – A case study from a coastal terrain setting in New Zealand

“…Ref. [30]), a practical challenge for the wind energy industry remains related to the stochastic and intermittent nature of wind, which can make generation difficult to forecast over a range of time scales or impose supply-demand issues and additional costs [20,40]. The characteristics of time varying wind speed records at heights in the atmosphere relevant to wind turbines are strongly influenced by various atmospheric and climatic phenomena over a range of space-time scales.…”

Optimization of a PV–wind hybrid system under limited water resources

“…Nevertheless, both solar and wind resources are intermittent [11], thereby rendering them unattractive to many investors. One way of overcoming this limitation is through hybridization [11,12].…”

“…One way of overcoming this limitation is through hybridization [11,12]. In a hybrid system, several energy sources are integrated to provide the required amount of energy-thus, PV and wind resources can be combined to sustain energy supply to a load when one of these resources is not available.…”
