Distributionally Robust Unit Commitment in Coordinated Electricity and District Heating Networks
IEEE Transactions on Power Systems, 2020Coordinated operations of electricity and district heating networks offer a potential for mitigating inherent variability of renewable energy sources (RES) in the ongoing transition to smart grids.

Unit Commitment With Flexible Generating Units
IEEE Transactions on Power Systems, 2005In today's volatile environment of restructured power markets, and with the passage of more stringent Clean Air Act Amendment of 1990, competitive generation units must have the ability for operating under flexible conditions to respond to various market driving forces.

Unit commitment is the process of deciding in advance whether to turn on or off each generator on the power grid at a given hour. In order to illustrate the changing nature of unit commitment as the electric power industry moves into a deregulated market, a broad form of the unit commitment problem for the present environment is first presented.

To capture the stochastic characteristics of renewable energy generation output, chance-constrained unit commitment (CCUC) model is widely used. Conventionally, analytical reformulation for CCUC is usually based on simplified probability assumption or ...

Sequential timestep unit commitment
2001 IEEE Power Engineering Society Winter Meeting. Conference Proceedings (Cat. No.01CH37194), 2002This paper presents a method for solving the unit commitment problem sequentially in time. By decomposing the problem in time, each timestep is solved individually using a free market model of the power system. The corresponding market clearing handles both energy demand, primary reserve demand and secondary reserve demand, and is performed using an ...

The authors present a thermal unit commitment method for interconnected multiarea power systems. The method is a natural extension of the commitment utilization factor (CUF)-based single-area unit commitment method. CUF is extended to reflect the impact of multiarea transmission interconnection constraints on the utilization efficiency of committing a ...

Unit commitment literature synopsis
IEEE Transactions on Power Systems, 1994Several optimization techniques have been applied to the solution of the thermal unit commitment problem. They range from heuristics such as complete enumeration to the more sophisticated ones such as Augmented LaGrangian. The heuristics have even reappeared as expert systems.

Resilience Constrained Day-Ahead Unit Commitment Under Extreme Weather Events
IEEE Transactions on Power Systems, 2020Over the last years, extreme weather events have caused extensive damages in power systems, leaving millions of customers without electricity and therefore highlighting the necessity to enhance power system resilience.

The paper describes a new and rigorous method for determining the mode of operation of an electrical power system that minimizes the operational cost. The power system consists of M thermal generating units and one constant-head hydroplant. The operational cost includes the fixed and variable start-up and running costs of the thermal units.
