Oil and natural gas are deleting in unprecedented rate in our growing economy. As global warming and raising oil prices push our existence into disrepute, many have turned to nuclear energy for many years to fill this need. Though nuclear disasters happened in the past; it was the most recent outbreak at Japan’s Fukushima nuclear power station in 2011 that gotten many countries to reconsider the continuing use of nuclear energy. This incident propel the Singapore government to research and develop alternative energy resources. Having no natural resources but depended only on the import of crude oil and natural gas to power its generators, it has embarked on using intermittent and non-intermittent green energy sources to power homes and industries. Program that encourage demand response implemented by the Energy Market Authority in 2013, earmarked for a more resilient and robust power system and a competitive market pricing of electricity for consumers and operators. It is for the successful implementation of these initiatives that the power management of a microgrid which harness the energy from micro sources and the power grid to feed the different load centres are being studied. Control strategy that uses real/reactive and voltage/frequency schemes to manage power flow when the microgrid operates in grid-connected or islanded fashion help to ensure such a system is viable and sustainable. Together with the use of three simulation using the Matlab Simulink software, we seek to understand how power can be managed within a micro-grid to ensure quality and reliable power supply for everyone.
