Research on the Economic Benefits and Operational Strategy Optimization of Photovoltaic- Energy Storage- Direct Current- Flexibility Building

The PEDF building model is crucial for advancing the global energy transition, reducing greenhouse gas emissions, and increasing economic benefits. However, due to its long-term advantages, users often overlook its immediate impacts, hindering widespread adoption. This paper presents three optimization strategies: AC/DC energy-saving, regulation response, and economic operation. A comprehensive evaluation system quantitatively compares these strategies. Simulations show that the regulation response strategy outperforms in stabilizing grid loads and mitigating fluctuations, while the energy-saving and economic strategies are less effective in grid stability.
