Paragraph starter

The optimal allocation of photovoltaic (PV) and battery energy storage systems (BESS) within unbalanced distribution networks is critical for enhancing grid performance. Research by Ray et al. (2024) demonstrated that employing optimization algorithms like the multi-objective Pelican optimization algorithm (MOPOA) can lead to significant reductions in power loss (up to 16%) and improvements in voltage stability (up to 4.4% reduction in VUF) by strategically placing PV and BESS. This highlights the importance of considering network unbalance and time-of-use pricing when designing renewable energy integration strategies.
