Abstract Wind power producers face many regulation costs in deregulated environment, which remarkably lowers the value of wind power in comparison with the conventional sources. One of these costs is associated with the real-time variation of power output and being paid in frequency control market according to the variation band. In this regard, this paper presents a new approach to the scheduling and operation of battery energy storage installed in wind generation system. This approach depends on the statistic data of wind generation and the prediction of frequency control market prices to determine the optimal charging and discharging of batteries in real-time, which ultimately gives the minimum cost of frequency regulation for wind power producers. The optimization problem is formulated as the trade-off between the decrease in regulation payment and the increase in the cost of using battery energy storage. The approach is illustrated in the case study and the results of simulation show its effectiveness.

Frequency oscillations due to large load disturbance can be effectively damped by fast acting energy storage devices, because additional energy storage capacity is provided as a supplement to the kinetic energy storage in the moving mass of the generator rotor. The energy storage devices share the sudden changes in power requirement in the load. This paper deals with the concept of Load Frequency Control (LFC) in a deregulated power system considering Battery Energy Storage (BES) system. Time domain simulations are carried out to study the performance of the power system and BES system. The performance of the power system under realistic situation is investigated by including the effects of Generation Rate Constraint (GRC) and governor Dead Band (DB) in the simulation studies.

"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."
