TITLE:

Monitoring the voltage imbalance caused by the injection of solar energy in the low voltage network: A study through the infrastructure of public lighting in the municipality of Marechal Deodoro

KEY WORDS:

energy injection from photovoltaic panels, public lighting, telemanagement relay, monitoring, voltage imbalance and voltage level.

BIG AREA: Engenharias
AREA: Engenharia Elétrica
SUMMARY:

Brazil's and the world's energy matrices are in an energy generation decentralization process due to the Distributed Generation (DG) expansion resulting in the energy generated through Photovoltaic Panels (PV) installed on the roofs of residences in urban areas. This change has made the energy quality monitoring for the Low Voltage Distribution Networks (LVDN) one of the Distribution System Operators (DSO) biggest challenges, who are only aware of the energy quality levels through the customers' complaints to the distributors. The author is not aware of any system implementation project for this purpose, possibly due to the high investment required for this technology. Therefore, this research proposes a monitoring cyber-physical system that will monitor voltage levels and Voltage Imbalance between phases. The proposed system will provide the DSO's energy with real-time information regarding the LVDN through a low-cost data acquisition model, using the public lighting infrastructure through Telemanagement relays. The system will be validated in an empirical study that analyzes the voltage imbalance and its levels when energy is injected through the PV through three single-phase frequency inverters installed in three different homes, each one connected to a different phase of the LVDN. In addition, the study will analyse the voltage in a Distribution Network (DN) fed by a transformer close to the DN transformer that has energy injection generated by the PV and verifies if there is interference in the phases voltages and if this interference causes Voltage Imbalance. It is expected that the results of this project would bring relevant contributions to the energy quality levels monitoring challenge, thus collaborating for a more orderly expansion of Brazil's energy generation distribution.
