PROJECT GOAL: TO DEVELOP, INTEGRATE, AND DEMONSTRATE IN AN EMS VENDOR SYSTEM WITH ISO-SIZE DATA, A STOCHASTIC, DECENTRALIZED AC UC AND OPF SYSTEM THAT SUPPORTS SECURE OPERATION OF BULK ELECTRICITY GRIDS WITH HIGH PENETRATIONS OF IBRS. PROJECT OBJECTIVES: THE PROJECT SEEKS TO ACHIEVE THE FOLLOWING PROGRAMMATIC OBJECTIVES: 1. MODELING: TO DEVELOP STEADY-STATE PHASOR MODELS FOR IBR AND ENERGY STORAGE SUITABLE FOR RESOURCE SCHEDULING. 2. ALGORITHMIC DEVELOPMENT: TO DEVELOP A STOCHASTIC, DECENTRALIZED ALGORITHM THAT CAN OBTAIN SOLUTIONS FOR THE LARGE-SCALE ISO AC UC AND OPF PROBLEMS ONE ORDER OF MAGNITUDE FASTER THAN BUSINESS AS USUAL (BAU) AS ESTABLISHED CURRENTLY BY THE ISOS. THE SPEED GAINS ARE LARGELY DUE TO THE PARTITION OF THE SYSTEM INTO SMALLER REGIONS THAT SOLVE ITERATIVELY UNTIL GLOBAL CONVERGENCE IS REACHED. 3. TESTING: TO TEST AND VALIDATE THE ALGORITHM IN THE GEORGIA TECH LABORATORY FOR A VARIETY OF IBR USE CASES. 4. INTEGRATION: TO INTEGRATE THE ALGORITHM INTO THE VENDOR EMS SYSTEM PLATFORM. 5. DEMONSTRATION: TO DEMONSTRATE THE SOFTWARE ON THE VENDOR EMS ENVIRONMENT WITH UTILITY DATA. 6. COMMERCIALIZATION: TO VALIDATE CUSTOMER-MARKET FIT, EVALUATE THE BUSINESS CASE, AND DEVELOP A POST-PROJECT COMMERCIALIZATION STRATEGY FOR THE UNITED STATES MARKET.
