1 Why regional optimization matters

Renewable energy systems are not one-size-fits-all solutions. Different regions have different climatic conditions, natural resources, energy demands, and grid characteristics that affect the performance and feasibility of renewable energy sources. For example, solar power may be more abundant and cost-effective in sunny and dry areas, while wind power may be more reliable and productive in windy and coastal areas. Regional optimization aims to match the renewable energy source with the regional characteristics, maximizing the benefits and minimizing the drawbacks.

2 How to assess regional potential

The first step to optimize renewable energy systems for specific regions is to assess the regional potential of different renewable energy sources. This involves collecting and analyzing data on the availability, quality, and variability of the renewable energy resource, as well as the existing and projected energy demand, grid capacity, and infrastructure. For example, for hydroelectric generation and storage, you would need to evaluate the water flow, elevation, reservoir size, and environmental impacts of potential sites, as well as the load profile, transmission lines, and market prices of the region.

The assessment of a region's renewable energy potential is critical for long-term energy planning. It necessitates a thorough examination of: - Resource Availability: Gather data on the energy source, such as sun irradiation, wind velocity, etc. - Quality and Variability: Recognize seasonal or hourly fluctuations that may impact energy production. - Energy Demand: Examine the facility projected energy consumption patterns. - Grid Capacity and Infrastructure: Examine the present grid's ability to accommodate increased or variable renewable loads. - Site-specific Data: Reservoir size, elevation, potential environmental implications, etc. - Economic Considerations: Market prices, transmission costs, and any regional incentives or tariffs.

The assessment can be performed with in-situ measurements, remotely sensed, or reanalysis data. For example, mast measurements and reanalysis products (such as MERRA-2 or ERA-5) can be used for wind energy potential. For further reading: Olauson, J. (2018).

3 How to design regional systems

The second step to optimize renewable energy systems for specific regions is to design regional systems that match the regional potential with the technical and economic requirements. This involves selecting and sizing the renewable energy components, such as turbines, generators, inverters, batteries, and controllers, as well as the interconnection and integration options, such as grid connection, islanding, or hybridization. For example, for hydroelectric generation and storage, you would need to choose the type and capacity of the hydroelectric plant, such as run-of-river, pumped storage, or micro-hydro, as well as the optimal operation and control strategies, such as peak shaving, frequency regulation, or load following.

To design a regional system: - Use design and modeling tools available to quantify the expected performance. - Use the historic weather and geographical data and use them as inputs in the design tool. - Consider having accurate cost models, as costs (material cost, shipment, installation, labors, etc.) are location and market dependent. - Consider techno-economic analysis. Several studies in the scientific literature focuses on the performance while neglecting the associated cost.

4 How to evaluate regional systems

The third step to optimize renewable energy systems for specific regions is to evaluate regional systems based on the performance and impact criteria. This involves simulating and testing the regional systems under different scenarios and conditions, such as weather patterns, demand fluctuations, grid disturbances, and policy changes. For example, for hydroelectric generation and storage, you would need to measure and compare the energy output, efficiency, reliability, resilience, and cost-effectiveness of the regional systems, as well as the environmental and social impacts, such as water quality, biodiversity, and community participation.

5 How to improve regional systems

The fourth step to optimize renewable energy systems for specific regions is to improve regional systems based on the evaluation results and feedback. This involves identifying and implementing the best practices and opportunities for improvement, such as upgrading the renewable energy components, optimizing the operation and control algorithms, enhancing the interconnection and integration features, or expanding the regional systems. For example, for hydroelectric generation and storage, you would need to monitor and adjust the water flow, turbine speed, generator voltage, and battery state of charge, as well as to coordinate and cooperate with other renewable energy sources, grid operators, and stakeholders.

6 How to learn from regional examples

The fifth and final step to optimize renewable energy systems for specific regions is to learn from regional examples that have successfully implemented and optimized renewable energy systems. This involves studying and replicating the best practices and lessons learned from other regions that have similar or different characteristics and challenges. For example, for hydroelectric generation and storage, you would need to look at the examples of Norway, Brazil, China, and Canada, which have different levels of hydroelectric development, potential, and integration with other renewable energy sources.

This is why collaboration is important. Countries like China and Brazil can do skill transfer to other countries seeking to improve their hydroelectric generation and storage. The road to global sustainable energy is 'paved' with cooperation.

One of the major ways to improve PV production that is not well exploited is to always deploy bifacial panels whenever there is a considerable distance underneath and to explore and deploy adequate reflective material. The cost to go from single sided panels to bifacial panels is usually negligable and exploiting albedo effect effectively can reducw project ROI, increase annual yield and density.
