Abstract
Efforts to mitigate emissions have led to the introduction of more distributed and volatile generation, such as photovoltaics, along with flexible and smart loads. This shift strains the reliability of power distribution systems (PDSs), which are expected to adapt to these challenges. Volatile energy sources further affect the interaction between medium-voltage (MV) and low-voltage (LV) levels in PDSs. Hence, distribution system operators need novel strategies for efficient capacity enhancements.
The distribution expansion planning (DEP) problem seeks optimal PDS design, minimizing investment and operational costs while meeting service requirements. Existing literature on DEP often overlooks the interplay between LV and MV systems. However, isolated investment plans may not remain optimal (or even feasible) for integrated MV/LV systems, necessitating coordinated models. This work addresses the gap by exploring coordinated DEP for MV and LV systems with volatile energy sources.
We leverage spatial aggregation techniques for large-scale planning. To evaluate the proposed approach, we utilize representative PDSs in Switzerland. This research enhances the adaptability and efficiency of modern PDSs amidst the increasing deployment of distributed and volatile energy sources.
