  3. Abstract:
  4. In the new environment of power system, generating units dispatch problem plays an important role inasmuch as it is used to clear power market transactions. That is, market operator solves an optimization problem in order to find the energy and capacity reserve quota of each generating units participating in the power market. There are different techniques for solving this problem which differ in many aspects, including the objective function, optimization algorithm, and feasibility, so using an efficient technique is vital. In the real competitive electricity market, the components of generating units dispatch problem are faced with the uncertainties; therefore, due to the presence of uncertainty and inaccuracy in the data, fuzzy set theory may be appropriate to model these uncertainties. In this paper, a modified fuzzy generating unit's dispatch is formulated to solve the problem under the simultaneous electricity market. Also, the required spinning reserve is optimally provided considering load interruption cost. The formulated optimization problem it then solved using the evolutionary programming (EP) that is a near global stochastic optimization method. These concepts are illustrated by application to the IEEE reliability test system (IEEE-RTS)
