Electronics Nuclear engineering The power fluctuation problem of renewable energy sources, frequency and voltage deviations are usually occurred in the isolated power systems, in which the ability to maintain stable supply-demand balance is low. Smart grid system is a solution to this problem and because of that the idea of smart grid concept is proposed which cooperatively could balance the supply-demand between power supply side and power demand side. The installation of photovoltaic (PV) system is proposed in a residential building which can be straight forwardly connected to DC sources. DC systems are required to bring lower costs by elimination of inverter and rectifier circuits and it may be possible to operate the PV system with high efficiency. Therefore, this study presents a DC smart grid system for a small residential network that sourced by solar energy which consist of a PV generator, a solar collector (SC), a heat pump (HP) and a battery. Battery and heat pump are used as controllable loads. Then, in order to minimize the interconnection, point power flow fluctuations and its operational cost, Tanaka’s Optimization and Tabu Search Approach is employed. Tanaka’s Optimization is used to obtain the optimal operation of thermal unit and controllable loads. Meanwhile, Tabu Search approach helps to control the power consumption of controllable load and discharge and/or charge output of the battery. From the results it has been found that the interconnection point power flow in the smart house could be controlled within the given bandwidth from the power reference. By smoothing the interconnection point of power flow, the electricity cost could be reduced due to reduction of contract fee with the electricity power company. Consequently, we can expect high quality power supply, higher efficiency of power transfer and lower CO₂ emissions. 2021 Thesis http://eprints.utm.my/id/eprint/98305/ http://eprints.utm.my/id/eprint/98305/1/ZamiraJamilMSKE2021.pdf application/pdf en public http://dms.library.utm.my:8080/vital/access/manager/Repository/vital:144582 masters Universiti Teknologi Malaysia, Faculty of Engineering - School of Electrical Engineering Faculty of Engineering - School of Electrical Engineering
