REZs and Pumped Hydro Viability

I need a comprehensive analysis on how Australia can strategically maximize the potential of its Renewable Energy Zones (REZs) to export energy. The focus should be on energy storage and distribution, specifically through pumped hydro storage.

Key requirements include:
- Assessing technical and economic feasibility using PowerWorld to model energy flow and system performance.
- Analyzing cost and economic viability of pumped hydro storage.

Ideal skills and experience:
- Expertise in energy systems modeling and economic analysis
- Proficiency in PowerWorld
- Background in renewable energy and energy storage technologies

My project is focused on exploring how Australia can strategically maximize the potential of its Renewable Energy Zones (REZs), to export energy to countries I’m planning to assess both the technical and economic feasibility of using Ultra High Voltage Direct Current (UHVDC) transmission lines for long-distance export, as well as integrating hydro pumped storage to ensure reliability.Use simulation tools such as PowerWorld to model energy flow, system performance, and financial viability.
