The use of, both, static as well as dynamic compensators together may give cost-effective reactive power compensation for predefined transient limits of voltage response. This paper presents the pricing of reactive power compensation under steady-state and dynamic conditions of a system with fixed capacitor (FC) and STATCOM.
Although switched capacitors are cost-effective, it is almost impossible to achieve full reactive power compensation with them. Other tools that their reactive power outputs are fully controllable are expensive solutions.
This paper reviews different technology used in reactive power compensation such as synchronous condenser, static VAR compensator, capacitor bank, series compensator and shunt reactor, comparison between them, source of reactive power and different optimization techniques.
Due to the high demand for energy, reactive power compensation aids in preventing power system overloading and collapse [2,3]. Conventional methods, such as synchronous condenser systems, have been proven effective in the past for improving power factor and supplying reactive power [4, 5].
The circuit diagram of compensation capacitors and peripheral hardware in the implemented hybrid reactive power compensation system is also given in Fig. 7. As can be seen in this figure, there are six single-phase and two three-phase capacitors. Rated powers of each capacitor are also shown in the same figure.
The controller, after some calculations, decides on the capacitor stages closest to these powers and activates them. However, after the capacitors are switched on/off, unlike conventional capacitor switched compensation systems, the reactive powers drawn from each phase of the grid must be of the same type.
