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.
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

Development of an Integrated Solar Photovoltaic-thermal (PVT) Module for the Tropics
This was Singapore government (MOE/EDB) funded R&D project in collaboration with Grenzone Pte Ltd and NUS. The project aims to design and develop a novel and compact PVT collector and its smart management system that integrates
solar PV and solar thermal systems to achieve improved overall energy efficiency and energy density.
4.6kW Solar-Wind-Hybrid Standalone System
This system is for research on solar and wind hybrid operation. It is composed of the following: 2.1kW solar PV system, 2.5kW wind generator and energy storage. The system converts both solar and wind energy into electrical
energy for electrical appliances in the laboratory or is stored in the battery bank.
19.2kW Grid-connected Solar Photovoltaic System
This system is to study the performance of a PV system connected to the power grid. It consists of four 4.8kW mono-crystalline solar PV systems. The systems are connected to a low voltage grid and supply the power to the teaching blocks.
The system has been operating successfully since its installation.
48.88kW Solar Photovoltaic Test Bed (EDB CERT project)
The test bed consists of two different systems: one with 10 different PV technologies and another with 13 different installations. The main objectives of this EDB project are to study the performance of various PV technologies in the
tropical region and to investigate the impact of different installations on the energy yield of PV system in Singapore.
