Implementation of modified chaos embedded symbiotic organisms search algorithm to solve economic dispatch problem / Mohamad Khairuzzaman Mohamad Zamani ...[et al.]

With the increase in fossil fuel prices, power system
operators were facing a challenge to reduce the operational cost
since it is directly related to the consumer electricity price. To
counter the issue, the optimal power output of generation units
were obtained by solving economic dispatch problem. In past
years, various researchers have attempted to solve the problem
using different optimization technique. However, several
optimization techniques failed to produce a high-quality solution
due to the drawbacks of the optimization process. This paper
presents a new optimization technique termed as modified chaos
embedded symbiotic organisms search technique in the attempt
to produce a higher quality solution. The proposed technique was
employed to solve economic dispatch problem on a 26-bus IEEE
reliability test system (RTS) at several case studies. Comparative
studies with respect to PSO, EP and AIS has yielded that the
proposed algorithm has proven its superiority over the other
optimization technique.
