| Abstract: | In today's grid power system, the emergence of flexibility devices such as energy storage systems (ESS), static synchronous compensators (STATCOM), and demand response programs (DRP) can help power system operators make more effective and cost-effective power system scheduling decisions. This paper proposes security-constrained unit commitment (SCUC) for stochastic scheduling of power systems based on the grid and the coordinated strategy of ESS, STATCOM, and DRP units in the presence of high solar PV power penetration. By addressing the problem constraints, the goal is to reduce operational, ESS cost, load shedding, solar power curtailment, and DRP costs. The AC power flow equations and all the model relations have been given convexities to produce a mixed-integer quadratically constrained programming (MIQCP) model, the solution to which would produce global optimum results. The developed model is used for solving the general algebraic modeling system (GAMS), realistic to the IEEE 24-bus system in several case studies, and the outcomes are carefully examined. The economic benefits shared by ESS and DRP with STATCOM devices were reduced by about 5.6% in scheduling costs as compared to solar PV farms. [ABSTRACT FROM AUTHOR] |
