A VERY FAST AND EFFECTIVE NON-ITERATIVE “h - LOGIC BASED” ALGORITHM FOR ECONOMIC DISPATCH OF THERMAL UNITS

Abstract

In this paper a very fast and effective non-iterative “Alogic based” algorithm for Economic Dispatch of Thermal units has been presented. As this is a direct or noniterative method it does not demand any initial guess value of A for ED (Economic Dispatch) of units for given Pdemond (=Po). Many of the existing conventional methods fail to impose P-limits at violating units. Improper selection of initial value for il may cause slow convergence or at times leads to divergence for the conventional algorithms. Further, each specified Po the problem is to be attempted afresh with new guess value of A. If the load various from (Po)min to (PD)max on the plant having K-units, the solution time becomes significantly larger for higher values of K. Unlike to this. the proposed algorithm always offers the solution in an non-iterative mode with very low solution time as it is computationally very fast. The proposed algorithm is tested on K=38 units and results reported in the paper
