Development of Web-Based Real-time Energy Monitoring System for Campus University

This study presents development of real time energy monitoring system installed in Level 17, Tower 2, Engineering Complex, Universiti Teknologi MARA (UiTM), Malaysia. The device and programming uses microcontroller board Arduino, ESP8266 Wi-Fi module, sensors and Emoncms.org web server to record and display the real time power and energy consumption, energy cost, energy index and CO2 emissions. The device allows 3 phase measurement of energy use in the building level where the main power source has been divided into several loads such as lighting, power plug, and Air Conditioning (AC) fan. The device is capable to transmit the data at set time interval using Wi-Fi communication and logging directly to local SD card for further analysis. The device was calibrated using FLUKE 485 power meter concurrently to meet a good reliable result with lower tolerance. The device was installed and tested during testing period including weekdays and weekend to see hourly energy performance in the particular building level. It is found that the device provides reading with average error of 2.04% as compared to commercial meter during one week testing period

Analysis potential benefit of energy cost the chiller plant operation engaging with tariff scheme

Engagement with new tariff scheme, Enhanced Time of Use (EToU) after switching from old tariff scheme, Time of Use (ToU) for chiller plant operation may be not promising a significant benefit for consumer in term of techno-economic value or even getting worse. This uncertainty condition make consumers doubt to switch onto latter. Therefore this study is focusing to analyze and looking potential benefit of energy cost the chiller's plant operation when engaging with the new tariff scheme EToU rather than ToU. Consumer's potential benefit appear for this study when switching from ToU to EToU tariff scheme for chiller plant operation through shifting the chiller's plant operation from peak to mid-peak hour while maintaining discharging operation of thermal energy storage (TES). This could benefit both consumer's on demand and utility on supply side respectively. Consumer may experience lower energy cost charged by utility. While utility could minimize the investment cost to install and maintain power system infrastructure in order to meet energy demand as well. However, further comprehensive study on this paper is also discussed for looking the more significant benefit to reduce energy cost of chiller's operation when engaging with EToU tariff scheme
