SOLAR POWER FOR ENHANCING CAPACITY

The Present Scenario :

In almost all developing countries including India, the status of Electricity

supply is as follows:

Availability - Extremely Poor

Continuity - Highly intermittent in nature

Quality - Very poor, full of fluctuations with

Harmonic distortions present

SOLAR POWER FOR ENHANCING CAPACITY

Sources of Electricity - Grid / Diesel – Generator Set ( DG Set )

Type of Loads - Mostly Motor Starting Loads, Lights and Fans DG Set Selection - 2.5 Times of normal Load due to Motor

Load

Grid Connection - At least 1.5 times resulting into high fixed charges meaning higher cost per unit.

Main operating costs - Electricity bills through Grid Fuel costs and its transportation.




Present Scenario


Conclusion

Above is true not only for RURAL / REMOTE installations but even in URBAN India.

This results into loss of revenue, equipment reliability and users using Diesel Generator Sets (DG Sets) at lower operating power which means costs of unit going up to Rs 18-25 per unit.

Also larger cold storages need to be planned to offset such expenses .

In large number of Cold Storages used exclusively for Potato , they remain

Closed for 3-4 months in a year which could otherwise been used.

Limitation on use of smaller cold storages in remote areas due to Grid wire

Extension which is a costly affair.

So the solution lies in DISTRIBUTED GENERATION i.e.

ANALYSIS OF GRID-EXPORT SOLAR INVERTER UNDER ROOF-TOP

Advantage :

• High conversion efficiency of PV Power into usable AC power

• Simple system with longer life i.e. no battery life issue.

Disadvantages:

• Works only under net-metering or with certain Load Vs

generation ratio only

• Under 3Ph unbalance, the energy generation suffers

• Normally inverters synchronize with grid only, hence do not

convert PV power into usable energy with small DG .

. Can not be used in Stand – alone mode .

Present Scenario


Conclusion

Conclusion

• Major operating expenses (OPEX) are cost of electricity and fuel

• Electricity availability and its quality are a major concern

• Solar Solution with GRID-TIE inverter is not a good solution

• Solar Power + storage + Power Electronics offer the most cost effective solution with 4-6

years of payback period

• Major Subsidy(~30%) available through different agencies
