Chapter 10 - Testing of influence of SVC and energy storage device’s location on power system using GAMS

Abstract

In this chapter, the testing of the influence of static Var compensator (SVC) and energy storage device's location on the power system using the general algebraic modeling system—GAMS will be presented. First of all the program, GAMS will be described. The structural organization of the program model, the speed of convergence, the comparison with other optimization techniques, and some of GAMS's solvers will be discussed. On the other side, the basic information about SVC and energy storage devices will be presented. Concretely, different types of energy storage as well as their connection with the power network, and the trend of use will be described shortly. In addition, the structure of SVC devices and their impact on the network will be discussed. The main part of this chapter will be oriented on the location of the storage and SVC device's influence on power system losses and voltage deviation, respectively. For those testings, the IEEE 9-test bus system will be used. By using GAMS, for all network nodes, the optimal value of storage active power, as well as SVC's reactive power, will be found for two cases: case without, and case with the wind farm. All results will be graphically presented, while certain parts of the realized GAMS program will be inserted.
