Genetic algorithms based economic dispatch for cogeneration unitsconsidering multiplant multibuyer wheeling

摘要

A new method based on genetic algorithms (GA) is proposed fornoptimal dispatch among multiplant (cogeneration systems) withnmulticogenerators, which transmit MW to designated buyers (load buses)nvia wheeling. The operation constraints in the cogeneration systems andnsecurity constraints in the third party (transmission system owner) werenconsidered. Varying weighting coefficients for penalty functions andndetermination of gene variables for GA were discussed. The IEEE 30- andn118-bus systems were used as test systems to illustrate thenapplicability of the proposed method
