APPLICATION OF ENERGY STORAGE SYSTEM (ESS) TO REDUCE DIESEL POWER CONSUMPTION AND IMPROVE GRID STABILITY IN PORT BLAIR

The island operates Diesel Generators (DGs) for source of power. In 2013 Port Blair authorities installed solar PV to reduce diesel consumption, but have not achieved expected savings as diesel generators also need to act as reserve due to sudden changes of solar output.

ESS INTEGRATION TO AVOID WIND CURTAILMENT

Installed capacity of the wind farm is considered as 20MW. Due to high seasonal fluctuation of wind, there is a high curtailment at different feeders at different hours. Most of the curtailment happens from 11 PM to 5 AM. Based on generation, different seasons have different levels of curtailment. In the higher windy months from June to October generation is higher; as a result curtailment is also higher. But in other seasons from November to April (low windy season), curtailment is also lower. Curtailment per turbine varies from 1200 MWh to 1800 MWh for different feeder lines. Read More...

ESS INTEGRATION TO OPTIMISE DIESEL CONSUMPTION (WITH CAPTIVE WIND PLANT)

Most parts of India suffer from significant power shortages. Southern region of India has around 20% of power deficit throughout the year. To ensure uninterrupted power supply almost all industries, commercial complexes as well as residential buildings deploy diesel generator (DG) as back-up and emergency supply. The estimate varies between 25,000 to 35,000 MW for installed capacity of DGs in India. Though, current price trends might suggest lower diesel prices for next couple years, however, considering limited resources for oil and gas, diesel prices are expected to rise in long run.
