An Effective Allocation Method for Distribution Static Synchronous Compensator (D-STATCOM) Devices using an Improved Predator-Prey Brain Storm Optimization Algorithm in a Hybrid Code

This paper proposes an optimal allocation and output control method for D-STATCOM devices with Improved Predator-Prey BSO (IPPBSO) in a hybrid code. Although the deployment of Distributed Energy Resources (DERs) has been widely spread, they bring about uncertainties of renewables that do not smooth distribution system operation. Therefore, it is essential to take control of system conditions with some controllers. In this paper, D-STATCOM devices of D-FACTS are used as the controllers, which need the optimal allocation to determine the locations and output variables. This paper proposes an IPPBSO in a hybrid code that strengthens the solution diversity in Predator-Prey BSO (PPBSO). This paper presents an optimal method for the allocation and output control of D-STATCOM devices using an IPPBSO approach in a hybrid code. In this study, D-STATCOM devices, a type of Distribution Flexible AC Transmission System (D-FACTS), are employed as controllers that require optimal allocation to determine their placement and output parameters. The effectiveness of this approach is evaluated using the IEEE 69-node distribution system as a case study.
