Boosting Transmission System Flexibility in Network-Constrained Unit Commitment by Incorporating Distributed Series Reactors

In the recent decade, renewable energy sources (RES) such as wind and photovoltaic (PV) power generations gained more attention. However, despite their proven role in reduction of operating costs network, integration has some serious challenges inherent uncertainties balance at grid. Some options to face these challenges, well enhance network’s flexibility, are demand response (DR), distributed FACTS (D-FACTS) devices, storage systems (ESS). This paper focuses on solution unit commitment (UC) problem a way that addition increasing transmission operation cost network decreases. To do this, series reactors (DSRs) employed promising D-FACTS devices flexibility. The uncertainty RES is handled by scenario-based stochastic programming technique. A mixed-integer linear (MILP) approach developed, with guaranteed global optimal solution, developing convex model for flow presence DSRs. proposed UC implemented IEEE RTS 24-bus system, obtained results different cases show ability abovementioned flexibilities reduce network.
