The strengthening of electric energy security and the reduction of greenhouse gas emissions have gained enormous momentum in previous decades. The integration of large-scale intermittent renewable energy resources (RER) like wind energy into the existing electricity grids has increased significantly in the last decade. However, this integration poses many operational and control challenges that hamper the reliable and stable operation of the grids. This article aims to review the reported challenges caused by the integration of wind energy and the proposed solutions methodologies. Among the various challenges, the generation uncertainty, power quality issues, angular and voltage stability, reactive power support, and fault ride-through capability are reviewed and discussed. Besides, socioeconomic, environmental, and electricity market challenges due to the grid integration of wind power are also investigated. Many of the solutions used and proposed to mitigate the impact of these challenges, such as energy storage systems, wind energy policy, and grid codes, are also reviewed and discussed. This paper will assist the enthusiastic readers in seeing the full picture of wind energy integration challenges. It also puts in the hands of policymakers all aspects of the challenges so that they can adopt sustainable policies that support and overcome the difficulties facing the integration of wind energy into electricity grids.

“…In order to mitigate the negative impacts rendered by the integration of DG without unnecessary DG power curtailment and load shedding, energy storage systems (ESSs) have been identified [3]. With proper planning and management, the ESSs also can offer diverse applications in DNs, including (i) peak shifting and load leveling [4,5], (ii) renewable power output smoothing and time shifting [6], (iii) frequency modulation [7], (iv) dynamic reactive power compensation and voltage regulation [8], (v) grid expansion and upgrade deferral [9], (vi) network congestion management [10], (vii) network reconfiguration/islanding [11,12], (viii) black start and reserve [13], etc. Among various means of energy storage technologies, battery has been selected as the energy storage unit in this study due to the technology maturity and applicability.…”

Energy storage system (ESS) has been advocated as one of the key elements for the future energy system by the fast power regulation and energy transfer capabilities. In particular, for distribution networks with high penetration of renewables, ESS plays an important role in bridging the gap between the supply and demand, maximizing the benefits of renewables and providing various types of ancillary services to cope the intermittences and fluctuations, consequently improving the resilience, reliability and flexibility. To solve the voltage fluctuations caused by the high permeability of renewables in distribution networks, an optimal capacity allocation strategy of ESS is proposed in this paper. Taking the life cycle cost, arbitrage income and the benefit of reducing network losses into consideration, a bilevel optimization model of ESS capacity allocation is established, the coordination between active/reactive power of associate power conversion system is considered, and the large scale nonlinear programming problem is solved using genetic algorithm, simulated annealing and mixed integer second-order cone programming method. The feasibility and effectiveness of the proposed algorithm have been verified.

“…The necessity of adding battery banks for energy storage is considered the primary drawback of stand-alone charging stations. The reason for such a drawback is the high installation and maintenance costs, the relatively short life-span when frequently charged and discharged, and the high cost of the associated energy conversion power electronics [18,19]. Several attempts to extend the life-span of lithium-ion batteries have been made in previous studies, for example by using battery degradation prediction methods for the reliable estimation of a battery's state of health (SOH) [20,21] and optimizing charging patterns to increase the efficiency and the life-span of lithium-ion batteries [22][23][24].…”

Wind-Energy-Powered Electric Vehicle Charging Stations: Resource Availability Data Analysis

et al. 2020

The integration of large-scale wind farms and large-scale charging stations for electric vehicles (EVs) into electricity grids necessitates energy storage support for both technologies. Matching the variability of the energy generation of wind farms with the demand variability of the EVs could potentially minimize the size and need for expensive energy storage technologies required to stabilize the grid. This paper investigates the feasibility of using the wind as a direct energy source to power EV charging stations. An interval-based approach corresponding to the time slot taken for EV charging is introduced for wind energy conversion and analyzed using different constraints and criteria, including the wind speed averaging time interval, various turbines manufacturers, and standard high-resolution wind speed datasets. A quasi-continuous wind turbine’s output energy is performed using a piecewise recursive approach to measure the EV charging effectiveness. Wind turbine analysis using two years of wind speed data shows that the application of direct wind-to-EV is able to provide sufficient constant power to supply the large-scale charging stations. The results presented in this paper confirm that the potential of direct powering of EV charging stations by wind has merits and that research in this direction is worth pursuing.
