Power & Sustainable Energy Hub

About the Tech hub 

The Power & Sustainable Energy Hub is equipped with solar and wind power stations and modern smart power networks (micro-grids and smart grid) to provide students with a platform on which they can learn and build up capabilities and skills in the design, operation and maintenance of various power and energy systems through hands-on exercises or final year projects.

The hub seeks collaboration with industry and academic/research institutes in joint research and development (R&D) and industry projects involving staff/students to improve competencies in the area of electrical power, renewable energy applications, energy efficiency, micro-grids, smart grid, etc. In addition, the hub also provides customised courses to retrain and upgrade manpower for electrical power and renewable energy industries.

The Power & Sustainable Energy Hub is located at levels 1 and 4 @T12 and level 2 @T8, Singapore Polytechnic.

Capabilities and Technical Services

Supported by the vast experience of the members, the Power & Sustainable Energy Hub provides technical consultations, training, seminars and project collaborations to government agencies, educational institutes, businesses and industry partners in these technology areas:

  • Energy systems
  • Solar photovoltaic systems
  • Wind energy
  • Micro-grids and smart grids
  • Electrical power systems

In addition, we also provide customised courses to retrain and upgrade manpower for the relevant industries.

Project Showcase

The Energy & Rapid Transit Hub promotes a wide array of applied R&D projects undertaken by students and staff. Some of the achievements and past projects are shown below:

Miniature Smart Gauge for AC Distribution Board

The project developed a Miniature Smart Gauge (MSG) that has miniature size and din rail mounting case. It can measure up to four current channels with non-intruding current transducers (CT). The measured data is reported wirelessly with Zigbee (MSG1) or Wifi (MSG2) technology. All these features make it not only easy to install in the household DBs, but also provide the potential for the future smart applications like cloud application and big data analysis.

DC Microgrid System for Smart Grid Performance Enhancement

This was Singapore government (EMA) funded R&D project in collaboration with SP PowerGrid Ltd. The project aimed to develop an intelligent, modularly designed grid-connected DC micro-grid control system. Such a system minimizes the negative impact of the distributed renewable energy that are generated from solar PVs and wind turbines, and enhances smart grid performance in terms of system efficiency, stability and reliability through the developed smart power management units and system controllers.

AC/DC Hybrid MicroGrid System

MicroGrid system, a modern concept for a small-scale localized electricity generation and distribution system, has been developed and operated by students in SP. The system, integrating different energy sources and energy storages, is able to operate in two different modes: "island" mode" and "grid-connected" mode to provide both 240 VAC and 24 VDC electrical power in a lab setup.

Mobile Micro-Grid Management System

This was Singapore government (MOE) funded R&D project in collaboration with ST Kinetics Ltd. The project aims to develop a standalone mobile power network management system that is capable of integrating multiple small generator sets as well as small renewable energy resources. This was done through smart controls with power electronics-based converters, resulting in a mobile microgrid power system with high power capacity and energy efficiency.

Real-World Test-Bedding of Integrated Smart Green Technologies

This was an Iconic Project funded by Singapore Polytechnic. The project aimed to develop IoT technologies with emphasis on energy efficiency. First time in Singapore, a system of integrated smart green technologies of the following 5 parts had been designed, developed and implemented in a real-world full-operational clubhouse (SPGG - Singapore Polytechnic Graduate Guild) for energy efficiency and sustainability. Some key technology merits and innovativeness are highlighted below:

  • Improved overall energy efficiency whilst providing the office best human comfort through smart facility management
  • The 40 kW solar PV system installed helps the clubhouse to save energy consumption by 55,200kWh per year
  • IoT-based dynamic water flow monitoring for water consumption profile management
  • Improved building wall/window energy efficiency through the use of high-performance thermal insulation and self-cleaning coating materials
  • One-stop IoT central monitoring and control with interactive dashboard interface
