“…Most of the injected voltage, which is in quadrature with the line current, provides the effect of inserting an inductive or capacitive reactance in series with the transmission line. The variable reactance influences the electric power flow in the transmission line [6]. Figure 3 shows the functional model of SSSC which includes an energy storage device as dc capacitor in order to allow power exchanges like real or reactive power with the electrical network.…”

“…SSSC has several advantages over the conventional one due to its storage element. Also, the main control objective of the SSSC is to directly control the current and indirectly the power flowing through the line by controlling the reactive power exchange between the SSSC and the AC system [6]. The SSSC circuit model has a voltage source converter (VSC), DC capacitor and a coupling transformer.…”

Abstract. This paper describes an approach powers flow control for an electrical network connected with a wind farm. In this work the powers flow control are performed through a Static Synchronous Series Compensator (SSSC) which is one of among Flexible AC Transmission System devices (FACTS). The wind farm is based on doubly-fed induction generators (DFIG). The simulation results show the effectiveness of the proposed approach making better the damping of power oscillations caused by the wind farm, ensuring the minimizing system transmission losses while providing a best voltage level. The simulations are done in MATLAB/ Simulink/ SimPowerSystems environment.

“…With continuing changes in power systems, notably electricity market deregulation, increasing interconnection and wider use of the less predictable renewable energy sources, the need for development of STATCOMs and other FACTS devices, such as Synchronous Series Compensator (SSSC), Unified Power Flow Controller (UPFC), becomes ever more pressing. Important aspects are the selection of installation locations, the selection and optimal parameter tuning for STATCOM and other FACTS devices, to deliver high performance control of voltage and power and damp out disturbances during transient states [4][5][6]. On the other hand, world-wide interest has been drawn to Modular Multi-level Cascaded Converters (MMCC) as possible next-generation inverters for STATCOMs and many other applications [7][8][9] in medium and high voltage (11 kV up to 200 kV) power systems.…”

This paper compares the operating capabilities of STATCOMs based on Modular Multilevel Cascaded Converters (MMCC) using star and delta connections, with special attention to unbalanced load compensation. Zero sequence voltage for star connection, and zero sequence current for delta, need to be applied to overcome the phase cluster DC-voltage unbalance. Expressions are derived for both zero sequence elements as functions of the degree of load unbalance defined as the ratio of negative to positive sequence load current. They show that the zero sequence voltage in star connection reaches a very high level as the degree of load unbalance increases, making the MMCC DC-link voltage too high for correct functioning. However the delta connected MMCC can cope with the high level of load current unbalance. Experimental results are presented to validate this analysis.

“…Nonetheless, they tend to present a slow convergence. Some applications of metaheuristics for conventional PSS tuning are: genetic algorithms, ant colony optimization, bat algorithm [11], cuckoo search algorithm [12], gravitational search [13], particle swarm optimization [14], bacteria foraging optimization [15], grey wolf optimization [16], and water cycle algorithm [17].…”

Decentralized Robust Saturated Control of Power Systems Using Reachable Sets

et al. 2018

Electric power grids are highly nonlinear complex systems. This manuscript presents a novel approach to the stabilization of large power systems. The proposed control satisfied three constraints: decentralization, input saturation imposed in practice, and robustness against load changes. The large power system is decomposed into subsystems, for each a decentralized controller is designed. The effect of the rest of the system on each subsystem is considered as an external disturbance and represented in norm-bounded form. A new approach to solve this problem is proposed in the present paper. The approach is based on the method of invariant ellipsoids, and the tool of linear matrix inequalities (LMI) is utilized to solve the resulting optimization problem. Control of multimachine power system is studied using the proposed control. Comparison with other techniques is also given.
