Abstract
The efficient management of power systems is becoming increasingly crucial as the demand for electricity rises and renewable energy sources are integrated. Ensuring system stability while managing costs presents a significant challenge for grid operators and planners. This study investigates the viability of using an equilibrium optimization algorithm (EOA) technique to determine the most effective distribution of multi-type Flexible AC Transmission System (FACTS) devices in order to maximize system security and reduce the annual investment expenditure on FACTS devices. In this process, voltage limits for buses and FACTS devices are considered as constraints, and two types of FACTS devices—Static VAR Compensator (SVC) and Unified Power Flow Controller (UPFC)—are analyzed: two cases, consisting of single-type devices (the same kind of FACTS devices) and multi-type devices (a combination of SVC and UPFC) are considered. In order to assign FACTS devices, simulations are performed on IEEE 30 bus test system using a load shedding technique to optimize costs. The simulations' outcomes are encouraging and may be useful for electrical restructuring.
