In this paper, a new security-constrained self-scheduling framework incorporating the transmission flow limits in both steady state conditions and post-contingent states is presented to produce efficient bidding strategy for generation companies (GENCOs) in day-ahead electricity markets. Moreover, the proposed framework takes into account the uncertainty of the predicted market prices and model...

This paper analyzes the computational performance of the deterministic optimization approach for the Security Constrained Unit Commitment problem (SCUC) addressing thermal generating units, that was developed in its companion paper. The technique proposed in the first part is based on suitable integer cutting planes, specific for the SCUC problem, and a Branch and Bound search which incorporate...

This study extends the agent-based 8-Zone ISO-NE Test System to include wind turbine agents, each characterized by location, physical type, and an output curve mapping local wind speed into wind power output. Increases in wind power penetration (WPP) are modeled as build-outs of investment queues for planned wind turbine installations. The extended system is used to study the effects of increas...

Power systems are shifted from conventional bulk generation toward renewable generation. This trend leads to the frequency security problem due decline of system inertia. On other hand, natural gas-fired units frequently scheduled provide operational flexibility their fast adjustment ability. The interdependence between power and gas is thus intensified. In this context, paper considers constra...

In the recent decade, renewable energy sources (RES) such as wind and photovoltaic (PV) power generations gained more attention. However, despite their proven role in reduction of operating costs network, integration has some serious challenges inherent uncertainties balance at grid. Some options to face these challenges, well enhance network’s flexibility, are demand response (DR), distributed...
