Streszczenie
The content discusses the increasing interest in DC technologies for energy efficiency and sustainability. It introduces an AC/DC optimal power flow method for hybrid microgrids, highlighting key performance indicators (KPIs) for techno-economic assessment. The study validates the approach using a real-world demonstrator at CEDER, showcasing promising results across different operating scenarios.
Key points include:
- Transition towards dynamic electric grids due to renewable energy integration.
- Microgrids enhance grid resilience and sustainability with distributed energy resources.
- DC elements offer efficiency benefits in integrating renewable sources without multiple conversions.
- AC technologies provide advantages like better voltage control and infrastructure abundance.
- Hybrid AC/DC microgrids combine benefits of both electricity currents for reduced emissions.
The study implements Python-based optimization techniques validated at TIGON CEDER, showing close alignment between calculated and measured values. Techno-economic assessments reveal profitability insights based on different operational scenarios, emphasizing the importance of flexibility in maximizing benefits while reducing costs.
