Participation to Frequency Regulation of Wind Power System with Spinning Reserve Control to Permanent Magnet Synchronous Generators (PMSGs)

"This study presents the modelling and dynamic simulation of an Isolated Wind Power System (IWPS) consisting of a Wind Turbine Generator (WTG), a synchronous machine (SM), consumer load, dump load (DL) and a Battery Energy Storage System (BESS). First the IWPS architecture and the dynamic models of the IWPS components are described. Second, the control requirements for frequency regulation of the IWPS are studied and a PID regulator to govern the active power stored+dumped by the BESS+DL combination or supplied by the BESS along with a power sharing algorithm between the BESS and DL is presented. Finally the IWPS is simulated facing to variations to load and WTG power. The simulation results are given showing graphs of the main electrical variables in the IWPS: system frequency and voltage and active power in each component. The results show how the BESS or BESS+DL combination regulates correctly the isolated system frequency. The results also show that the BESS improves the IWPS reliability when compared with the frequency control obtained using only the DL."

Currently, back-to-back converter is widely used in rectifier and inverter of direct-drive permanent magnet synchronous wind power system. But there are two shortages in the system, not stable of control effect and higher ripple of DC voltage. The dual-channel parallel boost converter can shunt the DC current, reduce the ripple effectively, and improve the quality of inverter side DC current. The paper uses the space vector pulse width modulation control strategy to control the inverter. Simplifying and decoupling the complex control system and control the DC bus voltage to remain stable. The simulation results confirm that dual-channel parallel boost converter have a better control effect than back to back converter, it through control the inverter to make power quality reached the grid connected requirement, verified the correctness of the design of inverter.
