RESEARCH ON FREQUENCY REGULATION STRATEGIES FOR WIND
Battery direction of wind power in communication base stations The paper proposes a novel planning approach for optimal sizing of standalone photovoltaic-wind-diesel-battery power
As of recently, there is not much research done on how to configure energy storage capacity and control wind power and energy storage to help with frequency regulation. Energy storage, like wind turbines, has the potential to regulate system frequency via extra differential droop control.
The paper presents a control technique, supported by simulation findings, for energy storage systems to reduce wind power ramp occurrences and frequency deviation . The authors suggested a dual-mode operation for an energy-stored quasi-Z-source photovoltaic power system based on model predictive control .
This study proposes a coordinated control technique for wind turbines and energy storage devices during frequency regulation to avoid secondary frequency drops, as demonstrated by Power Factory simulations .
The simulation results reported in indicate that a penetration level of wind energy of 17.91% combined with an energy storage system (ESS) keeps the frequency fluctuations of the electrical system within the permitted limits. The power system used in this reference is an IEEE 9-bus.
