the issue of unit commitment is one of the most important economic plans in power system. in modern and traditional power systems, in addition to being economical of the planning, the issue of security in unit operation is also of great importance. hence power system operation confronts units’ participation and input considering network security constrains. the issue of units’ participation is ...

This two-paper series proposes a novel deterministic optimization approach for the Unit Commitment problem (UC), more specifically for the Security Constrained Unit Commitment problem (SCUC) addressing thermal generating units. In the first part, a suitable mathematical programming model is presented, which contemplates all the inherent constraints and a single set of binary variables, i.e. the...

In this paper, the impacts of an incentive-based Demand Response, i.e., Ancillary Service DR (ASDR), and a price-based DR, i.e., Time of Use (ToU), are revealed in a restructured power system which has some wind farms. This network is designed based on the pre-emptive market which is a day-ahead market with a balancing market prognosis. It is a proper mechanism to deal with the stochastic natur...

Nowadays, the high penetration of renewable energy sources (RESs) with non-uniformly distributed patterns has created unprecedented challenges for regional power systems to maintain system flexibility and reliability. These technical obligate operators curtail part produced at various scheduling intervals. Motivated by these challenges, grid-connected hubs are seen as a way forward boost flexib...
