Abstract
The increasing penetration of variable renewable energy sources has significantly reshaped electricity price profiles in modern power systems. In many wholesale markets, the classical price “duck curve” is gradually evolving toward a pronounced mid-day price valley, driven primarily by the large-scale integration of photovoltaic generation. PV technology has become the most widely deployed renewable energy source worldwide due to its modularity, declining investment costs, and favorable policy support. However, the generation profile of PV plants is often poorly aligned with electricity price profiles.. This growing mismatch challenges the economic feasibility of PV-only investments and exposes investors to increasing market risks. As a response, battery energy storage systems are increasingly being coupled with PV plants to enable energy arbitrage to improve revenue streams. By shifting energy from low-price periods to high-price intervals, PV-BESS systems offer a promising pathway to restore and enhance profitability. At the same time, the large-scale deployment of such hybrid systems introduces new technical and operational challenges at the distribution network level, where voltage regulation, line loading, power flow reversals, and congestion management become critical concerns.This paper investigates the impact of PV plants equipped with BESS on the operation and performance of distribution networks. The analysis focuses on how energy arbitrage-driven charging and discharging strategies influence network constraints, voltage profiles, and power flows. The results show a trade-off between market-based profitability and distribution network security, highlighting that network constraints must be explicitly considered to achieve economic benefits from PV–BESS systems while maintaining reliable network operation.
