This paper presents a control strategy for a standalone wind-energy conversion system using Permanent Magnet Synchronous Generator (PMSG). The presented control strategy aims at regulating the load voltage in terms of magnitude and frequency under different operating conditions including windspeed variation, load variation and the unbalanced conditions. The wind generating-system under study consists...
A research on differences of latest Grid Code requirements for wind farm integration between China and selected EU countries are conducted. The similarities and differences of these Grid Codes in the aspects of active power/frequency control, reactive power/voltage control and fault ride-through capability are compared. The main causes of these differences are investigated and the author tried to...
This paper presents the dynamic operation and control strategies of a hybrid wind-diesel-battery energy storage based power supply system for isolated communities are investigated. Control strategies for voltage and frequency stabilization and efficient power flow among the hybrid system components are developed. The voltage and frequency of the hybrid wind-diesel system is controlled either by a...
Wind energy will play an important role in all future power supply concepts. Already today in some countries the contributions from fluctuating wind power have reached considerable high levels causing contingencies in the grid. This fluctuating power will significantly influence the operation of transmission and distribution systems as well as the operation of the conventional power plants. Therefore...
