Abstract
Concerned with the increasing greenhouse gases in the atmosphere due to fossil fuels, the entire world is focusing on electricity generation through renewable energy resources. The most advantageous aspect of the distributed renewable sources is to provide the electricity to remote, scattered and the deprived rural areas by developing the hybrid power system at the smaller scale where power transmission through grid extension is not viable due to some economical, technical or environmental constraints for building new transmission lines. An accurate and adequate control strategy becomes inevitable to uphold the smooth operation by restraining the frequency and voltage deviation within its limit ensuring the highest degree of reliability of hybrid power system to provide an adequate power quality. In this paper, a comprehensive review of different control strategies adopted in isolated and interconnected multi-area hybrid power systems is presented.
Highlights
Electricity requirement at every inch of our life is indispensable whereas the consequences of using conventional sources of electricity are catastrophic
A system developed with the help of Renewable Energy Sources (RES) and different energy-storing components (ESCs) requires a proper coordinating control mechanism which can be achieved by selecting the appropriate and intelligent soft computing algorithms like Genetic Algorithm (GA), Particle Swarm Optimization (PSO), Cuckoo Search Algorithm (CSA), and Mine Blast Algorithm (MBA)
The selection of the optimal parameters of the controllers under the influence of soft computing techniques according to the problems defined is essential to restore the system’s stability
Summary
Electricity requirement at every inch of our life is indispensable whereas the consequences of using conventional sources of electricity are catastrophic. HPS is permeating across the world rapidly to harness the free and abundant renewable energy at best which is of the utmost essential Still, these sources are climate dependent, from which arises some challenges like fluctuation in the power generation, voltage deviation, and frequency oscillation. Interconnection of the HPS with multiple sources improves the reliability of the power supply by complementing each other to a certain extent, attracting research attention worldwide On the contrary, these advantages are ascertained with some critical challenges like system instability due to uncertainties such as wind velocity and solar irradiances which are entirely climate dependent.
