Grid integration of a hybrid wind-solar street light

Municipalities face rising electricity costs, with public lighting accounting for up to half of these expenses. The adoption of energy-efficient solutions, such as light-emitting diodes and renewable energy integrations, offers significant cost savings and environmental benefits. This study demonstrates the feasibility of integrating a wind-solar hybrid street lighting system into the urban grid of Tokyo, ensuring reliable, stable, and safe operation. By utilizing advanced power flow and short-circuit analyses through the Newton-Raphson method in the electrical transient and analysis program software, the system consistently meets daily electricity demand while maintaining voltage stability within regulatory limits and providing sufficient fault protection. Additionally, the system generates surplus clean energy capable of reducing peak grid demand and lowering carbon emissions. These insights contribute valuable knowledge towards achieving sustainable and energy-efficient urban lighting infrastructure aligned with Tokyo's decarbonization goals.
