Integration of Wind Energy into Electricity Systems: Technical Challenges and Actual Solutions

Rotor Current Control Design for DFIG-based Wind Turbine Using PI, FLC and Fuzzy PI Controllers

“…Therefore, renewable energy sources have been incorporated in modern power systems to contribute in power production and to compensate for the growing energy gap. Particularly speaking, the power generated by wind turbines can affect the power systems operational security, reliability and efficiency [23], [24]. Hence, studying the consequences of the dynamic interaction between wind farms and electrical power systems is a crucial step before the real integration of wind farms into the grid.…”

“…Due to the high variations in the wind power generation at different timescales: hourly, daily, or seasonally, maintaining grid stability is considered highly challenging. These power variations result in voltage variations that can cause serious problems in the voltage stability, static security, and transient stability [23]. In order to achieve a reliable service, stable frequency, and to compensate for uncertainty and variability caused by wind turbines, several operating reserves are used by power system operators [24].…”

Wind – Hydro Coordination for Enhanced Worth of Wind Power and Potentials in Karnataka State of India

“…There are no generic solutions to enhance the worth of wind power. Besides the solution is not always to build up a back-up system as suggested by many authors [5,6,7] but rather to make use of the existing dispatchable sources in required manner depending on the geographical conditions. Wind power being non dispatchable and hence having reduced worth can be coordinated with other dispatchable sources of energy in a specific manner for its enhanced worth.…”

Design of Wind/Diesel Generator Micro-Grid Power System in Kano, Nigeria, Using Homer

“…[15] reports from [16] that 'high penetration of wind energy creates stability problem, and possible blackouts', as well as creating 'more stress on breaker, transmission line, bus bar at the time of fault occurs, due to high penetration of wind energy resources' [15]. Also, 'electric utility system planners and operators are concerned that variations in wind plant output may increase the operating costs of the system' [17]. As such, a system with single turbine has been chosen as the most appropriate system because is simpler, and easy to maintain when compared to system with two and three turbines.…”
