Stochastic Electric Power Generation Unit Commitment in Deregulated Power Market Environment
Utilities participating in deregulated markets observe increasing uncertainty in load (i.e., demand for electric power) and prices for fuel and electricity on spot and contract markets. This study proposes a new formulation of the unit commitment problem of electric power generators in a restructured electricity market. Under these conditions, an electric power generation company will have the ...
متن کاملAn adaptive modified firefly algorithm to unit commitment problem for large-scale power systems
Unit commitment (UC) problem tries to schedule output power of generation units to meet the system demand for the next several hours at minimum cost. UC adds a time dimension to the economic dispatch problem with the additional choice of turning generators to be on or off. In this paper, in order to improve both the exploitation and exploration abilities of the firefly algorithm (FA), a new mo...
متن کاملSolving the Unit Commitment Problem Using Modified Imperialistic Competition Algorithm
One of the most important problems for power system operation is unit commitment (UC), for which different constraints should be satisfied. UC is a nonlinear and large-scale problem; thus, using the evolutionary algorithms has been considered for solving the problem. In this paper, the solution of the UC problem was investigated using Modified Imperialistic Competition Algorithm (MICA). Simula...
متن کاملSolving the Unit Commitment Problem by a Unit Decommitment Method
In this paper, we present a unified decommitment method to solve the unit commitment problem. This method starts with a solution having all available units online at all hours in the planning horizon and determines an optimal strategy for decommitting units one at a time. We show that the proposed method may be viewed as an approximate implementation of the Lagrangian relaxation approach and th...
متن کاملSolving the Unit Commitment Problem in Power Generation by Primal and Dual Methods
The unit commitment problem in power plant operation planning is addressed For a real power system comprising coal and gas red thermal and pumped storage hydro plants a large scale mixed integer optimization model for unit commitment is developed Then primal and dual approaches to solving the optimization problem are presented and results of test runs are reported
