4.1 Cases for MAED

This thesis explain the two cases of multi-area economic load dispatch (MAED). The first cases is a two-area system with four generating units and the second cases is four-area system with sixteen generating units.

4.1.2 A four-area system with sixteen generating units. Now here I describe a four-area system with sixteen generating units with the help of tie-line.

4.3 Test System-II: Four area with sixteen Generators.

Here there is four-area system and sixteen generator units with active tie-lines [17, 22]. The active load demand are set to 400 MW for area 1 ( P_1,P_2,〖 P〗_3 and P_4 units), 200 MW for area 2 (P_5,P_6,P_7 and P_(8 ) units), 350 MW for area 3 (P_9,P_10,P_11 and P_12 units ) and 300MW for area 4 (P_13,P_14,P_15 and P_16 units), The obtained result of MFO algorithms is shown in TABLE II. Here total load demand is taken 1250 MW. The solution obtained by the MFO algorithm is a feasible solution (∑▒P_g =1250.0MW) compared with results reported in literature by method such as the PS (pattern search) method (∑▒〖P_g=〗 1249.9982MW [23]), HHS (hybrid harmony search) method (∑▒P_g =1249.29MW [17]), HSLSO (hybrid sum local search optimizer) method (∑▒P_g =1250.0MW [24]).
