The interdependency of electric and natural gas systems is becoming stronger. challenge how to meet various energy demands in an integrated system (IES) with minimal cost has drawn considerable attention. optimal scheduling IESs ideal method solve this problem. In study, a day-ahead model for IES that included electrical system, hub (EH), was established. proposed EH contained detailed models t...

Some electric power markets allow bidders to specify constraints on ramp rates for increasing or decreasing power production. We show in a small example that a bidder could use an overly restrictive constraint to increase profits, and explore the cause by visualizing the feasible region from the linear program corresponding to the power auction. We propose two penalty approaches to discourage b...

The connection between various energy types in the integrated power and natural gas system has grown stronger recent years, as penetration rate of clean energy. Wind generation volatility offers a considerable barrier to operation. This research provides multi-time scale economic dispatch model with flexibility limitations address this issue. Through chance-constrained programming, equipment is...
