This paper introduces a step towards enhancing
the performance of an existing AI-technique known as
Harmony Search (HS). The original HS suffers from some
disadvantages and shortages which motivate the
researchers to develop newest variants as will be seen
later. Each variant tries to solve and overcome the
shortages of the previous one but still leave some
shortages behind it. Here, the research work had been
devoted to merge all the advantages of HS variants
together, and the disadvantages of them had been
excluded to introduce a novel technique which is more
effective in the optimization problems. The proposed
novel optimization technique is applied to design local
PID controller for Load Frequency Control (LFC) single
area power system. Comparative study is carried out
between the basic HS variants and the proposed one
using diverse tests in case of linear and nonlinear systems
to reveal the robustness and effectiveness of the proposed
algorithm.
