摘要

The asymmetrical scenery of renewable sources (RESs) has raised renewable insecurity. As a result, it is dominant to introduce energy storage systems (ESSs) along with DRP to lighten the instability of uncertain RESs. The combination of FACTs such as static synchronous compensator (STATCOM) and Compressed air energy storage (CAES) both provide impending advantages for the power system including better system stability, improved voltage profile, and lower network obstruction. Other schemes are being deployed to increase control of power flows and optimize energy storage capacity. Furthermore, the need for DRP and CAES synchronized with STATCOM devices to ensure minimizes operational cost and system security makes the SCUC problem more demanding to solve due to the increasing problem size. In this perspective, the paper proposes a problem on stochastic SCUC with STATCOM devices, DRP, CAES and renewable sources. The modeling of the STATCOM devices within the power system in AC network is more intricate and finding a best possible location is discussed. The reduced problem size mitigates the burden arising from the combinatorial nature of the difficulty. The speed-up and optimality of the decomposed method are proven on the IEEE- 30 bus systems.
