“…However, it is possible to optimize the input or output of reactive power dispatch using D-FACTS. These systems can contribute to control voltage levels, as well as improve system reliability [27], [28]. So, it is necessary to define the maximum value of susceptance capacitive (which will be represent the injected reactive power to the grid), , and the minimum value of susceptance capacitive (which will be represent the absorbed reactive power from the grid), .…”

Distribution networks are suffering a transformation process with the insertion of distributed energy resources, changing from a passive part of the power grid into an active system. Aiming to reduce the challenges for the distribution system operators to keep the power grid operating inside of the quality levels it is possible to propose some ancillary services. Optimum Power flow is an optimization method used to plan the distribution grid operation. Additionally, the distributed energy resources can be modeled on it and ancillary services provisioning can be considered, as proposed in this work. In this way, the objective of the present work is to formulate a Multiperiod Optimum Power Flow (MPOPF) with the insertion of distributed generation, energy storage systems, microgrids, and electric vehicles at the distribution grid. This MPOPF considers the provisioning of ancillary services by the inverters associated with the equipment connected to the main grid. In the formulation, the entire grid is modeled, considering the placement of classic equipment as a voltage regulator and capacitor banks, in addition to modern technologies as DFACTS and four-quadrant inverters. The MPOPF was simulated for several scenarios considering a 90-bus test feeder and a real distribution grid from Curitiba -Brazil. From the results, the MPOPF proved to be highly robust, being able to simulate the grid with all the equipment connected simultaneously, performing the optimal dispatch of active and reactive power, as well as allowing the operation of ancillary services such as voltage support, peak-shaving, and demand-side management.

“…For example, in [10], the enhancement of voltage regulation capability is analyzed by installing a static synchronous compensator (STATCOM) system, parallel-connected with the DFIG-based wind generation system. Another example, in [11], the authors demonstrated the contribution of Distribution-STATCOM (D-STATCOM) for increasing the voltage stability margin of gridconnected DFIG-based wind power plants.…”

This paper proposed a Hybrid PI-Fuzzy based Static Var Compensator for minimizing voltage deviations as the integration of wind power generation to the distribution network. Hybrid PI-Fuzzy Logic controller constructed by the cascade-connected conventional PI controller and Fuzzy Logic controller. This algorithm combined the advantages and minimized the disadvantages of each conventional controller. The control method applied to the Static Var Compensator, which functioned as a dynamic reactive power source. The controlled dynamic reactive power source influenced the system with proper reactive power value, which resulted in the voltage regulation. Two scenarios were carried out to investigate the efficacy of the proposed method. The first scenario demonstrates the performance of the proposed system in wind speed variations and the second scenario in load variation conditions. Finally, the comparisons with Fuzzy Logic Controller-based self-tuning PI control were made to investigate the performance of the proposed control method. Simulation results verified that the proposed control algorithm outperformed the FLCbased self-tuning PI controller, in terms of the steady-state voltage deviation minimization by 1.47% and the settling time of the voltage respond decrement by 92.78%.

“…[21] The STATCOM generates an AC voltage, due to which a current of variable magnitude flows at the point of common coupling(PCC) in the transmission system. This current is nearly quadrature with the line voltage, thus at PCC an inductive or a capacitive reactance is connected in the transmission system [6] and provides the required real power and reactive power compensation [8].This method can be used to reduce the power quality issues and improve fault ride-through capability of a wind farm [20] [22]. Controller design for dc-dc converters [23][24][25] Fig.1shows the block diagram of the system with STATCOM circuit which is the 3ɸ inverter and a DC source which is connected with the transmission system wherethe voltage has to be compensated.…”

Due to unpredicted non-linear loads, power quality problems, a raise in the transmission system. One such problem is voltage sag. Voltage sag is caused by the non-linear load which demands reactive power, but the balanced 3 source provides required reactive power of the load with reduced voltage at the receiving end. In this paper, simulation study has been performed to reducethe voltage sag issue. A transmission system with generation source with different loading conditions is considered and study has been done. A 3 medium  model transmission line is designed with a power source of 11kV. A shunt connected compensation unit called Static Synchronous Compensator (STATCOM) reduces the voltage sag in the transmission line. STATCOM provides the required reactive power demanded by the non-linear load along with the source for compensation of voltage sag. The STATCOM circuit comprises of Voltage source converter(VSC) unit and a DC source. Reactive power compensation is done by VSC unit firing angle control. The source of the STATCOM can also be from renewable energy system. This AC source is converted by a AC-DC-AC converter unit.The firing angle is controlled by the control unit which ensures the continuous and balanced power flow even under sudden change in load conditions. The simulation results depict the characteristics of the developed STATCOM.
