Certain investigations on power management systems for standalone and grid interactive hybrid power supply

INTRODUCTION

1.1 BACKGROUND

The power sector of India is the fifth largest in the world. The

power sector has grown enormously from the installed capacity of 1363 MW

during independence in August 1947 to 258701.46 MW as of 31st January

2015. Of this, 180361.89 MW i.e. 69.71% of the generated energy comes

from thermal power plants which emit large amounts of greenhouse gases and

enhance global warming. The share of various renewable energy sources

(RES) based power plants amount to 31692.14 MW, which is just 12.25% of

the total installed capacity. Primarily wind power dominates the RES-based

power generation systems (PGS) and as of 31st January 2015, it accounts for

21151.36 MW, i.e. 8.17% of India's total installed power capacity, and it

generates 1.6% of the country's power (Central Electric Authority (CEA),
