Dynamic Real-Time Optimization of Microgrids with Day-Ahead Commitments for External Power Exchange

摘要

This paper explores the stochastic scheduling of microgrids where energy exchange with the macrogrid is constrained by day-ahead commitments. These constraints are included to reduce the added cost to distribution system operators, associated with the integration and operation of behind-the-meter generation. Chance-constrained optimization is used to minimize operational cost and meet the energy exchange commitments. The problem is transformed into a mixed integer linear program, and is used to analyze the impact of risk aversion on microgrid operating cost and renewables curtailment.
