ORTIZ PIMIENTO, NESTOR RAÚL  and  DIAZ SERNA, FRANCISCO JAVIER. VALIDATION OF SOLUTIONS OBTAINED FOR THE HYDROTHERMAL ECONOMIC DISPATCH PROBLEM USING MIXED BINARY LINEAR PROGRAMMING. Dyna rev.fac.nac.minas [online]. 2008, vol.75, n.156, pp.43-54. ISSN 0012-7353.

This paper refers to a design of a methodology that is capable to evaluate the exactitude of piecewise approximation used in the restriction of hydroelectric generation in order to resolve the hydrothermal economic dispatch problem while using mixed binary linear programming. The exactitude of the estimate value of hydraulic power depends on how reliable the solution is. Therefore, this methodology uses as decision criteria the average relative error to evaluate the quality of the obtained solution. This methodology has been applied in a corporation that must supply an energy demand in a medium term planning horizon. In addition, the company must have possession of one hydroelectrical and two thermal generation centers.

Keywords : hydrothermal dispatch; mixed binary linear programming; measurement error; piecewise approximation; nonlinear effect; hydroelectrical generation.
