“…However, the gain of the inertia controller has not a direct interpretation in the case of non-rotating technologies, like PV, BESS, electric vehicle (EV) charger stations, etc. Some scientific papers as [7], [11] has applied the concept of inertia controller to BESS, but instead of taking kinetic energy from the rotating masses, the controller enables to discharge the battery in a controlled way producing an additional power in the form of inertial power (P syn ).…”

This paper presents a probabilistic assessment of the effects of the fast acting power (FAP) controller of BESS in the system frequency response of a multi-machine system. Monte Carlo simulations and time-domain simulations, using DIgSILENT® PowerFactory TM are combined in the implementation of the proposed methodology. Simulation results show the effect fast-acting power controller of BESS in the system frequency response of a multi-machine system in the form of probabilistic distribution functions (PDF) of the main system frequency response.

“…However, the natural inertia of the wind turbine can be decoupled with the main grid when it connects through power electronic interfaces. Hence, the total amount of natural inertia can be reduced in a RES dominated power system, leading to frequency instability risks due to sudden active power imbalances [1]. To enhance the frequency stability of the power system, extra frequency control methods are required to overcome unprecedented frequency stability challenges.…”

“…Hence, the frequency is settled earlier after optimization, which means the power difference between FDWG generations and the power flows delivered by FDWGs located buses 7 and 9 to load 8 ( and ) is balanced faster. According to swing equation (1), frequency drop is prevented after power balance. Therefore, faster controller response is one reason to explain why VSP has a higher settled frequency after optimization.…”

Modeling and Optimal Tuning of Hybrid ESS Supporting Fast Active Power Regulation of Fully Decoupled Wind Power Generators

The frequency stability of the power system is challenged by the high penetration of power electronic interfaced renewable energy sources (RES). This paper investigates the improvements of the frequency response of fully decoupled wind power generators (FDWG) by proposing a novel generic model implementation of ultracapacitors (UC) within a hybrid scheme in real-time simulations of wind power plants. UCs are selected as ideal power sources in fast active power-frequency control due to their high power density and fast-reacting speed. Batteries and UCs combined hybrid energy storage systems (HESS) are formed to complement their characteristics. Droop-based and frequency derivative-based control and virtual synchronous power (VSP) are the selected control strategies to support power system frequency stability. The best trade-off between frequency performance and HESS cost is found by solving a proposed optimization problem formulation. The proposed optimization problem is used to define the HESS size and the controller parameters. The optimization results show how the fast active power-frequency response is enhanced by the fast UC power injection. It also shown that VSP leads to faster frequency support than the droop-based control and the frequency derivative control.
