Abstract EN
Economic load dispatch (ELD) problem is an important issue in the operation and control of modern control system.
The ELD problem is complex and nonlinear with equality and inequality constraints which makes it hard to be efficiently solved.
This paper presents a new modification of harmony search (HS) algorithm named as dynamic harmony search with polynomialmutation (DHSPM) algorithm to solve ORPD problem.
In DHSPM algorithm the key parameters of HS algorithm like harmony memory considering rate (HMCR) and pitch adjusting rate (PAR) are changed dynamically and there is no need to predefine these parameters.
Additionally polynomial mutation is inserted in the updating step of HS algorithm to favor exploration and exploitation of the search space.
The DHSPM algorithm is tested with three power system cases consisting of 3, 13, and 40 thermal units.
The computational results show that the DHSPM algorithm is more effective in finding better solutions than other computational intelligence based methods.
