“…Control structures that are well known in the literature [94][95][96][97][98] The control described above has been implemented with four regulators in [99][100][101], while in [102] it has been realised with only two for a system that is easier to tune and with reduced complexity. However, in the latter approach, a slight coupling has been detected and discussed by the author, which does not considerably affect the independent PQ control according to his demonstration.…”

Distributed energy storage systems (ESSs) are becoming essential components for the operation of the increasingly complex electricity grid, where dispersed generation is causing powerflows occurring both top-down and bottom-up. Specifically, the combination of ESSs coupled with application-specific control methods can achieve the interdependent objectives of system stakeholders such as the system operator, electrical utilities, retailers, equipment vendors, the government and the electricity customers. The necessity for an accelerated rate of transition to a multi-directional grid arrangement has been exacerbated by the rapid proliferation of distributed renewable energy sources (RESs) that are now price comparable to traditional supply sources. While there are review articles covering ESS technologies and applications as well as the plethora of future advanced grid arrangements that may eventuate, there is none which comprehensively covers individual and aggregated ESS applications and the corresponding benefits, comparing different technology selection methods and providing application-specific controls. Both operational and monetary benefits are identified and critically reviewed from the perspective of the aforementioned stakeholders. Wholesale and retail energy market regimes are also considered for monetisation of the benefits. The control methods that are provided cover both balanced and unbalanced grid conditions. This comprehensive review paper will be of immense value to researchers and practitioners seeking to understand and unpack the aggregated benefits of ESS in the electricity grid.

“…It is possible to perform input-output linearization on the dynamic model of the DFIGs with the use of the previously analyzed Lie algebra-based approach or with the use of the differential flatness theory-based approach. Next, state and disturbance estimation can be performed on the DFIGs' transformed model using the derivative-free nonlinear Kalman filter [59]- [62].…”

A control method for distributed interconnected power generation units is developed. The power system comprises permanent-magnet synchronous generators (PMSGs), which are connected to each other through transformers and tie-lines. A derivative-free nonlinear Kalman filtering approach is introduced aiming at implementing sensorless control of the distributed power generators. In the proposed derivative-free Kalman filtering method, the generator's model is first subjected to a linearization transformation that is based on differential flatness theory and next state estimation is performed by applying the standard Kalman filter recursion to the linearized model. Unlike Lie algebra-based estimator design methods, the proposed approach provides estimates of the state vector of the PMSG without the need for derivatives and Jacobian calculation. Moreover, by redesigning the proposed derivative-free nonlinear Kalman filter as a disturbance observer, it is possible to estimate at the same time the nonmeasurable elements of each generator's state vector, the unknown input power (torque), and the disturbance terms induced by interarea oscillations. The efficient real-time estimation of the aggregate disturbance that affects each local generator makes possible to introduce a counterdisturbance control term, thus maintaining the power system on its nominal operating conditions. Index Terms-Derivative-free nonlinear Kalman filtering, differential flatness theory, distributed power generation, electric power grid, nonlinear control, permanent-magnet synchronous generator (PMSG), sensorless control.

“…Alternatively energy sources are the energy sources different from those in wide spread use at the moments (which are referred to as conventional). Alternative energy sources include solar, wind, wave, and tidal, hydroelectric and geothermal energy [1]. Although they each have their own drawbacks, none of these energy sources produces significant air pollution, unlike conventional sources.…”

This paper investigates compensation of voltage sag due to faults in distribution system for a doubly fed induction motor(DFIG) configuration using dynamic voltage restorer(DVR). Series compensation of terminal voltage during fault conditions using DVR is carried out by injecting voltage at the point of common coupling to the grid voltage to maintain constant DFIG stator voltage. However, the control of the DVR is crucial in order to improve the FRT capability in the DFIG-based wind turbines.wind turbine is controlled by pitch angle which controls the rotor and stator currents of induction generator under different wind speeds. DVR injects voltage in series using vector control which compensates voltage quality problems. The proposed work is verified using matlab/ Simulink software.
