The Role of Photovoltaics in the Transition to a 100% Renewable Energy Supply

In countries accounting for 82% of the global electricity generation, photovoltaics and wind are already the cheapest source of electricity. It took 66 years until 2022 to install 1 TW of solar photovoltaic systems. However, the second TW will be reached in 2024 and an annual TW market will be reality before the end of the decade. This has a significant impact not only for the electricity system, but for our global energy supply as well. This Sub-Area addresses which technologies and concepts are available and most beneficial for the challenges of the energy transition.

The Inclusion Of Solar And Wind Power Into The Combined Renewable Energy That Is Integrated Into The Grid Will Continue To Revolutionize The Energy Sector, As Long As The Connection Criteria Are Met. Combining Solar And Wind Power Can Be A Good Alternative To Fossil Fuels. The Combination Of These Two Creates A Hybrid System, That Complements Each Other&Rsquo;S Strengths, And Reduces The Overall Variability Of The Power Supply. The Big Challenge That This Combination Faces Is The Diminished Power Quality From The Fluctuation Of Voltage And The Variation Of Frequency [5]. The Implementation Of Demand-Side Management Strategies Such As Peak Shaving And Load Shifting Can Help Align Demand With Variable Voltage And Fluctuating Frequency Supply. Government Policies, And Regulatory Frameworks That Promote Renewable Energy Development, Provide Financial Incentives, And Streamline Permitting Processes Can Accelerate The Adoption Of These Solutions. Combining Solar With Wind Energy Presents Challenges That Demand Initiative Solutions And A Holistic Approach To Energy System Planning And Demand- Side Management. Embracing Energy Storage Technologies Can Harness The Power Of Nature To Create A More Sustainable Future. Such Technologies Included In This Paper Are Supported By Policy Frameworks, And Demand-Side Management.

PV Deployment, Policy and Sustainability

Chair(s): Georgia Kakoulaki
The Global Energy Landscape Is Evolving Rapidly, Driven By A Growing Need For Sustainable And Clean Energy Sources. Nigeria, A Country Endowed With Abundant Sunlight And Significant Hydropower Potential, Is Positioned To Harness The Benefits Of Both Solar And Hydropower Technologies. Thus, Solar Farms On Land Requires The Use Of A Significant Amount Of Land. They Take Up More Space Than Traditional Power Plants And Are Not As Efficient. The Average Power Plant Occupies About 30 T0 40 Acres Of Land, Therefore This Research Work Presents, For The First Time, A Comprehensive Analysis Of The Design, Simulation, And Integration Of A 5Mwp Floating Solar Photovoltaic (Pv) System With The 760Mw Kainji Hydroelectric Power Plant As A Pilot Project For Capacity Expansion Of Mainstream Energy Solutions Limited (Mesl). This Innovative Project Explores The Synergy Between Solar And Hydropower Technologies To Maximize Energy Generation, Increase Operational Efficiency, And Reduce Carbon Emissions. The Engineering Design And The Sizing Of System Components And Performance Analysis Was Conducted With Pvsyst Software, And The Design Of The Support Structures Was Carried Out In Google-Sketchup. The Design, Simulations, And The Analysis Strongly Favor The Possibilities Of Establishing A Floating Solar Power Plant In The Kainji Dam. Additional Benefits Can Be Realized If An Appropriate Agri Voltaic Ecosystem Is Established.
