Designing A Load Agent For Power Management With A Multi-Agent Home Automation System Talat ÖZDEN Gumuşhane Vocational High School Gumuşhane University Gumuşhane, Turkey ozdentalat@gmail.com Halil İbrahim OKUMUŞ Department of Electrical and Electronics Engineering Karadeniz Technical University Trabzon, Turkey okumus@ktu.edu.tr Abstract—In this study, a load agent design is performed for the power management which lets us use existing electrical energy for consumer’s needs, comfort and criteria in the areas such as flats and commercial buildings that independently meet their energy need from renewable energy sources.The load agent is designed on the basis of radio-frequency communication so it is a wireless communication system which also has the ability of switching off or making power flow by measuring current of the load.The agent has a flexible structure in order to be compatible with all ambient equipments. It can work with all equipments on the system properly, without any hardware changing. And this is shown in the paper. Keywords-component; load agent; power management; mahas; home automation I. INTRODUCTION The rise in energy demand has brought economical and ecological problems in the modern world.. According to estimation of International Energy Agency (IEA), the energy demand of world will dramatically increase in rate of %55 between 2005 and 2030 and the increase of %84 in that ratio will be be derived from fossil fuels such as petrol, coil and natural gas [1]. The consumption of fossil fuels, which are finite resources, not only causes of energy crises but also causes of ecological ones. The usage of fossil energy resources is on the first rank on greenhouse gas emission, which causes global global warming. Significant rate of greenhouses gases are mainly related to energy sector. In the countries listed in the Kyoto protocol’s Sec.-B [2], energy sector’s greenhouse gas emission is established as %64. This rate could probably increase to %83 when the communication sector involved [3]. Therefore, it is of vital importance to use available energy resources efficiently and to use sources which has less greenhouse gas emission suc as carbon dioxide as it is described in the Kyoto protocol’s Sec.-B. The main resource of within easy reach renewable energy is sun. Solar radiation coming to world surface and absorbing by atmosphere is bigger 8000 times than energy primary consuming at world. When the total population of world is taken into account, this rate would unbelievably be 20 MW energy amount per person [4]. On the other hand, distribution of electric energy usage in Turkey during 2005-2006 was detected as; %24,36 for residence, %4.44 for street illumination, % 3,66 for government facilities, %2.56 for agriculture irrigation, %12.5 for business and % 52.43 for other consumption situations such as industry, worksite, etc. [5]. Small consumers such as flats which need less energy comparing to factories, worksites and other places consume %48 of total energy and this can be supplied by means of developed technology. 18.2% of the whole electricity consumption in 27 European Union countries is being met from the renewable energy resources [6]. Nevertheless, due to the equipments used in the systems producing renewable energy are still expensive, and besides energy resource is noncontinuous, usage rate of those still could not reach the inevitable point. But, lots of scientists have been doing important studies on handled energy in efficiency. In (Abras et al.), Multi-Agent Home Autonomous System allowing to agent operations in their own behaviors to handle optimum solution which is accepted for power management had been designed as simulation [7]. Again (Abras et al.), they presented their design MAHAS [8]. In (Ha et al.), presents a new three-layer household energy control system capable of both to satisfy the maximum available electrical energy constraint and to maximize user comfort criteria [9]. In (Jian et al.), Based on the idea of hierarchical coordinated control, an agent control model aiming at maximizing efficiency of Microgrid, is presented under the premise of voltage stability and power balance. The coordination control strategies of Multi Agent System (MAS) are also discussed [10]. Li (2004) and his friends, had presented a power management strategy, which make maximum power of output of panel in certain load and solar radiation and is resource tracing. They confirmed power efficiency in well- rounded measurement. Load matching which have being used against traditional solar energy system whose strategy improved power usage to 132% for portable system which can process image and communicate with wireless technology [11]. In this paper, a load agent which is necessary for power management system based on MAHAS design and material.
