Introduction:
This report presents an evaluation of the feasibility of a hybrid system combining
solar and biomass energy sources. The evaluation is conducted using HOMER
Pro software, a powerful tool for analyzing and optimizing hybrid power systems.
The main objectives of this study are to assess the technical and economic
viability of the proposed hybrid system, as well as its potential environmental
benefits. The results obtained from HOMER Pro simulations provide valuable
insights into the system's performance, cost-effectiveness, and sustainability,
enabling informed decision-making for implementing hybrid energy systems.
The depletion of conventional energy sources and the need for sustainable energy
alternatives have led to the exploration of hybrid energy systems. This report
focuses on evaluating the feasibility of a hybrid solar and biomass system, which
combines two renewable energy sources to provide reliable and clean power
generation. The HOMER Pro software is utilized to simulate and analyze the
system's technical and economic aspects, including component sizing, energy
production, and cost optimization.

3. Methodology:
Fig: Overview of Overall System
1. Define the study location and energy demand:
In this project we have basically tried to provide a feasible solution for DIU's
engineering complex under fixed load. Here we will see whether the hybrid
system is feasible or not.
2. Input parameters:
a) Solar & Wind data: For solar energy and wind data for this report, I fixed a
specific location like Daffodil International University and took its solar
radiation and wind velocity. Here at 45 degrees and the amount of shading is
less, it seems good to us. The average velocity of wind is 4.86 m/s which is
better than other area so we choose this area. Basically, we have taken all these
data from NASA's website.
b) Biomass data: To write the report we have collected the data from the farms
in the area about the gas produced from cow dung which is known as Boi
mass. Here we are 16.33 t/d from Annual Average Biomass Tons of bio waste
received per day. Inside which carbon content is 5% and gasification ratio is
0.70
c) Technology selection: Here we have fixed solar panels, converter bio
generator, wind turbine, wind generator considering the cost which is cost
effective and provides power supply to the load of 165.59 Kwh energy and
also supplies 23.3 kw during peak load.

Results and Discussion:
The HOMER Pro software generated the following results and insights:
1. Energy Production:
The simulation revealed the energy production potential of each renewable
source in the hybrid system. Solar panels generated an average of 1,090
kilowatt-hours (kWh) per year, wind turbines produced an average of 158,615
kWh per year, and the biomass generator contributed an average of 16,778
kWh per year.
2. Cost Analysis:
HOMER Pro conducted a comprehensive cost analysis, considering the
capital costs, operating costs, and maintenance costs of the system. The

10. software determined the optimal system configuration and sizing that
minimized the NPC. The feasibility of the hybrid system was evaluated by
comparing the NPC of the hybrid system with that of conventional energy
sources.
Fig: Optimization Result of Homer output
If we use only biomass generator in base case system then initial capital unit is
5,250 dollars. But total net present cost (NPC) is $ 49,623 dollars. Which is
relatively high. at the same time if we design the system using batteries from PV
array, wind farm, bio generator then the initial capital of the system is $6541
which is slightly more than the base case system. but total Net present cist (NPC)
is about 27% less than base case. So we are analyzing this proposal case as
feasible.
Fig: Cost Summary of the component for Optimization Result

11. The total net present cost (NPC) of a system is the present value of all the costs
the system incurs over its lifetime, minus the present value of all the revenue it
earns over its lifetime. Costs include capital costs, replacement costs, O & M
costs, fuel costs, emissions penalties, and the costs of buying power from the grid.
Revenues include salvage value and grid sales revenue. HOMER calculates the
total NPC by summing the total discounted cash flows in each year of the project
lifetime. Total Annualized Cost is the annualized value of the total net present
cost. The annualized cost of a component is the cost that, if it were to occur
equally in every year of the project lifetime, would give the same net present cost
as the actual cash flow sequence associated with that component. HOMER
calculates annualized cost by first calculating the net present cost, then
multiplying it by the capital recovery factor. Simple payback is the number of
years at which the cumulative cash flow of the difference between the current
system and base case system switches from negative to positive. The payback is
an indication of how long it would take to recover the difference in investment
costs between the current system and the base case system.
Conclusion:
Based on the analysis conducted using HOMER Pro software, the hybrid (solar,
wind, and biomass) system shows promise as a feasible and cost-effective
solution for meeting energy demands. The system demonstrated good
performance in terms of energy production and load matching while minimizing
the net present cost. However, further analysis, including a detailed economic
assessment and environmental impact evaluation, is recommended before
implementation.
