Roadway lighting was one of the earliest applications for electric lighting technologies. Well-designed roadway lighting offers many benefits and aids the visual tasks of drivers and pedestrians. Currently, the trend of energy management for exterior general lighting has increased in several cities. Generally, high-pressure sodium (HPS) lamps have been the standard throughout Thailand since the 1980s,...
The paper proposes the effects of multi-distributed generators (multi-DGs), which is integrated into the distribution system in terms of reliability indices and power losses. The distributed generators (DGs) under the study are connected to the distribution system at 22 kV of Thanyaburi substation on the Provincial Electricity Authority (PEA), which is a part of distribution system in Thailand. Multi-objective...
Since electrical energy is essential in human life, it is necessary to find out a way to reduce its consumption. In the past, in Thailand, they had to provide much energy to roadway lighting system because main lighting equipment has consumed high energy to generate lighting in the roadway. But today, we are increasingly aware of energy consumption. As a result, Light Emitting Diode (LED) luminaires...
