Abstract
Curbing CO2 emission is required for the global warming reduction effect. Human civilization is moving toward renewable sources to achieve this as early as possible. The electrical energy requirement increases day by day as with population and industrial growth. Therefore, more electrical energy saving and proper utilization of electricity are becoming essential. Nowadays researchers are moving toward, developing and demonstrating net zero emission (CO2 emission) renewable energy sources (like solar energy, wind power, Hydro plant and more) technologies. However, incorporating those energy sources in the electrical power grid, the grid becomes hybrid and complex. It is necessary for economic load dispatch (ELD) requirements that the hybrid grid must be optimized as well as utilized efficiently that results economical efficient energy saving. In this article, we contribute a solution toward efficient optimization applicable to moderate size generating stations (using renewable source for hybrid grid network). The presented work fulfills ELD requirement using hybrid harmony search and modified harmony search optimization. Renewable energy sources are a suitable options to meet the contingencies in conventional methods of electricity generation. Wind and geothermal power have the all-time availability and thus are the favorable clean energy sources. However, wind’s discontinuous behaviors effecting grid systems with unpredictable injection of power becomes a vital challenge to maintain good quality of the grid. Here the ELD requirement is prepared with the addition of renewable energy (wind) generation cost and thermal units. The penalty costs are being added for renewable power because of variability and uncertainty. Hybrid harmony search, ant colony, modified harmony search optimization and PSO are applied to the wind and thermal generating units (hybrid network) with an objective to get generation cost minimum to fulfill customer requirement. The proposed estimation is applied in twenty six Bus systems and simulation output data acquired with those optimization methods are compared among each other.
