Optimal location and size of SVC for power losses minimization and voltage security improvement

Abstract

This paper presents a procedure for determining the optimal location and size of Static VAr Compensators (SVC) in a power system. Two objective functions have been considered for solving the optimization problem: a) minimize a Voltage Performance Index (VPI); b) minimize the total active power losses and the investment cost of the compensators (SVC). The performances of installing one or two SVC devices were analyzed. The simulations were performed on the IEEE 30-bus network using a software implemented in under Matlab by the authors.

Optimal reactive power compensation in electrical distribution systems with distributed resources. Review

“…Among the static power reactive power compensator devices based on power electronics, the SVCs (previously described) stand out, which contain capacitance steps in parallel with reactances, both programmed by an automatic control system that decides whether the SVC should behave as a reactive generator and raise the system voltage, or behave as a load and absorb reactive from the grid by stabilizing the voltage levels to set parameters [ 28 , 29 , 30 ]. These devices inject a considerable harmonic component that must be taken into account in the global analysis of the problem of reactive power compensation, since it is a variable that conflicts with the purpose of optimization of reactive power flows.…”
