Analysis of power quality and economic worthiness of electric motorcycle charging in a residential electrical system

Abstract

In the urban society of Thailand, most people use motorcycles for travelling because they can meet the manoeuvrability of travelling in short distances and save energy compared to using a car. Many people are switching to electric motorcycles (EMCs), which install EMC chargers in their residential buildings. EMC chargers are power electronic devices that may produce electrical and electromagnetic interference; therefore, it is critical to evaluate the potential influence of an EMC charger on a household electrical system and other electrical equipment before installing one. Therefore, this study examined the effects of an EMC charger on residential electrical systems with and without a photovoltaic system connection as well as on individual load types in terms of power quality. The investigation revealed that EMC charging has a direct impact on the grid system's reactive power, power factor, and current harmonics. However, when the electrical load in the system has sufficient power, it is possible to reduce the reactive power and current harmonics of the grid. The cost of electricity when an EMC is connected to a residential electrical system was also analysed to determine the metre type and charging interval suitable for Thailand.

“…Only when all the power quality meets the requirements, the power quality can be judged as qualified. If any one of them is not qualified, then the whole power quality is not qualified [10]- [12].…”

Optimizing Cost and Emission Reduction in Photovoltaic–Battery‐Energy‐Storage‐System‐Integrated Electric Vehicle Charging Stations: An Efficient Hybrid Approach

“…Utilizing decision rules and demographic information, a novel method for determining the charging process allocation was used for the Austrian case study. Chiradeja and Nagopitakkal [ 17 ] have concentrated on the impacts of an EMC charger on different types of loads based on power quality and on household electrical systems that were linked to and disconnected from solar power systems. The study established that EMC charging directly affects the power factor, reactive power, and current harmonics of the grid system.…”
