1 IEEE - IBM Smarter Planet Challenge Smart Energy Saving System 1. Project Description Motivation - We live in a world with high costs of electricity. Burning fuel, coal, and petroleum produces electricity bringing us to a verge of extinction. With the daily increasing electricity consumption, we wonder if our coming generation will have to struggle due to the scarcity of electricity. This thought motivates us to develop a smart system which can not only efficiently use the available electricity, but also produce it with minimum of risk using the conventional sources, such as wing and solar energy. Project goals - The very basic goal is to find a better solution for power management and to invent new ways of producing electricity locally. First, we are focusing on cost reduction using Smart Management System [SMS]. Second, we focus on generating electricity locally using solar energy, as it is readily available globally. We could have also used wind power or ocean energy, however all of these are volatile and are not available in adequate amount everywhere. As we prefer solar as our input power to the system. The windy-cloudy weather plays the strongest role for the volatile nature of solar energy as a resource. In sum, we will propose this issue as one of our extent of problems. Smart Management System [SMS] - Our team believe that we need a power efficient system. i.e. a system, which should perform, if not more, same task with minimum power consumption. In order to fulfilling the world needs, we need to create better smart-fast and hazard free system to striving into green power energy. Henceforth, we propose to use rechargeable battery embedded with Smart Management System (SMS). To illustrate the working, take an example of refrigerator. Most of the power is wasted to maintain temperature inside it. Using SMS, once refrigerator reaches stable temperature, we will cut main power and power it with the battery during sufficient time intervals. Thus, helping to maintain its steady temperature state and hence reducing power consumption. SMS itself will help our valuable user, either industrial or residential people, to create better high efficiency of power consumption and distribution. Our SMS will include smart, safe and fast battery charging method to get recycled energy within an hour. We need power input, which will come from the solar system. Also United States government is giving 30% subsidies on solar, this will be much cost effective as it will reduce lot of our installation cost and thus make our product more economical. This is also very popular in customers as two million solar rebate forms were filled in less than five minutes on October 16th, 2012.

2 Innovative elements - We will perform the innovative elements of our system with the following key ideas: (i) the converted solar energy will be stored in the battery through the charge controller. Our smart management system will be responsible for fast charging method through solar panel. (ii) The next step of our implementation is to integrate the DC battery of solar panel system with our smart management system to the AC inverter. This current inverter is responsible for providing the electricity to some appliances. (iii) We will modify solar panel s current inverter from DC to AC before we start testing it on appliances. In this step, we will analyze solar panel battery and focus with system s safety optimization. (iv) Final step is to combine the entire system interface with smart management system interface and perform testing. 2. Project Details SMS presents combination of solar energy system and smart safe charging battery method. We will use sealed lead acid (SLA) battery as our power storage and supply. However, we noticed that this system would have a lot of challenges to reach the best storage performance. These challenges would be: Make charging method which is faster than 1/10 cycle timing Block heat transfer from solar panel to battery as heat may damage battery. Power and energy dissipation i.e. inverting problems (from AC - DC - AC) Our team proposed these challenges as our smart challenge. Other challenges that our team needs to do are create a simple data logger and battery analyzer. Data logger will help us to determine and help our first challenge. The purpose of data logger is to determine faster cycle signal for SLA battery charging. In the end, data logger and battery analyzer will work together as a single system. They will be used as screening tools to obtain faster charging timing. We will implement and join them into one compact system. If we don t have any information about how long does solar system charge the battery, then it will cause battery leaks. Excess charge of battery will cause permanent damage. We will pursue an adequate level of battery charging capacity. In this second problem, our solution emphasizes better optimization, which the battery capacity should show exact level that guard system obtained. This level will help to keep battery healthy and protect the number of battery cell. We can disregard heat transfer as the advantages of using our system. We will make this system become flexible, so users don t need to change their previous system. Users can add our proposed system without changing their industrial system. This is how our system will be built.

5 Implementation We will test our system in the campus neighborhood, such as campus housing where Florida Tech students live on campus, and Florida Tech Laboratories and Library. Benefit for Society Encourage society to use renewable energy resources, thus slowing down global warming. Reduce the cost of electricity. Eco-friendly (RoHS) and safe products to use around residential and industrial environment. Educational Purposes Create awareness of power management among students. Encourage students to do research in solar energy and practice using alterative energy. Reduce Florida Institute of Technology s electric bill for campus housing.
