Abstract: Small wind-solar hybrid systems are renewable energy systems that provide energy to retail customers like residential complex, factories, resorts, fuel stations and any other individual looking to reduce their dependency on state grid, solve energy access issues, reduce dependency on diesel or who just want to reduce their carbon footprint.
Fuel stations almost always depend on diesel for backup power in case of power outage. Not only is diesel expensive, but also polluting. There are approximately 53000 fuel stations in India and hence fuel stations represent a huge market for such renewable energy systems.
Fuel stations follow a standard design in case of power rating of pump, with only variation in the number of pumps. Lighting load is not very heavy. For simplicity, other amenities like ATMs are not considered in this report. Since they follow a standard design, it makes sense to design standard energy solutions for them. Hence the objective of the report is to facilitate wind-solar hybrid systems for fuel stations.
To design such solutions, accurate wind speed data is required which is a challenge. Since small wind turbines don’t have high hub heights like 50m-80m and require data at 20 m, wind speed data availability becomes challenging. Also, there is data discrepancy among sources. This report proposes a method to reduce the uncertainties in wind speed data.
Once the wind speed and solar energy data, comes the need to identify design parameters for designing solutions. After secondary research and market survey, power rating of pumps and lighting load were considered as basis for design. Wind speed and solar energy data was retrieved for 12 locations and combined with design parameters to arrive at three energy solution packages, each for three demand scenarios with the help of a excel based model.
The result from above exercise were three energy solution packages of 3.07kWp, 5kWp and 7kWp as a standard which could be designed on a case to case basis.
