In addition, since most renewable sources provide direct current (DC) power and the batteries used for storing power also give DC power, it is easier to integrate these sources into DC power line. The 48V DC power is stepped down to lower DC voltages (12–36V) with the help of converters to power the office and storage devices. Once 48V DC is primary wiring, one would require converters to power lower voltage appliances like PCs (which take 19V) and laptops and also TVs (some of them take 12V). Besides once in a while one may have to connect some legacy equipment which takes only AC input. The objective of this paper is to design an efficient and cost effective DC-DC power converter for notebook computers. The converter employs a synchronous rectified step-down DC/DC converter IC BD9611MUV to yield 19.5V DC from 48V DC input. The performance of developed power converter has been investigated under different input conditions and practical results have been reported in this paper. Also, this paper shows that existing large AC appliances can be connected to 48V DC line with the help of Microinverter.","PeriodicalId":339120,"journal":{"name":"2016 First International Conference on Sustainable Green Buildings and Communities (SGBC)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129608340","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Solar energy is clean, inexhaustible and environment-friendly resource among all renewable energy options. But neither a standalone solar photovoltaic (PV) system nor a wind energy system can provide a continuous supply of energy due to seasonal and periodic weather variations. Therefore, in order to satisfy the load demand, grid connected energy systems are now being implemented, that combines solar and utility grid, where the grid acts as an infinite like energy storage. In this paper a 10kWp grid tied roof solar system is implemented with a rechargeable energy storage system (RESS) in a home to overcome the frequent shut downs of the utility grid. In a country like India, the utility grid is shut down for few hours during the day time when the power from the solar is at maximum rate. During this shut down period, the energy from the solar system is stored in RESS apart from the loads connected in the home. The stored energy can be utilized during the night without taking much power from the utility grid. The power consumption from the utility grid can be nullified with the proposed system and in addition to this the excess stored power from the solar system is used for reducing usage of other energy purchases such as cooking gas and supplied back to the grid which is beneficial to the user. The proposed system is experimentally tested and the results are presented.","PeriodicalId":339120,"journal":{"name":"2016 First International Conference on Sustainable Green Buildings and Communities (SGBC)","volume":"17 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125355404","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Due to the highly variable nature of residential energy consumption, homeowners tend to oversize their generation and storage capabilities in order to meet their demand. We find the energy needs of many households are more efficiently met when neighboring homeowners pool their energy resources into an aggregate microgrid instead of relying solely on individually owned resources. We quantify the energy needs of individual residences and the aggregate microgrid by measuring net load variability. Using modified coincident factors, a conventional measure of variability in the electric utility industry, we calculate that the overall load variability for four southern Wisconsin households is reduced due to net load aggregation.","PeriodicalId":339120,"journal":{"name":"2016 First International Conference on Sustainable Green Buildings and Communities (SGBC)","volume":"82 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122723245","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This leads to significant reduction in total generation cost and emission levels. While introduction of Electric Vehicles (EV) in the grid can be looked upon as an additional load thus arising the need for increased generation, the price elasticity of EV load can serve as an opportunity to implement DSM. A V2G strategy is proposed to enable the reshaping of load profile by means of peak shaving and valley filling. By harnessing the energy storage of EVs batteries, an objective function is proposed for V2G control. Substantial savings and reduction in emissions along with reduction in peak demand, on implementation of this strategy, is evident from the simulation results. Optimal penetration level of EVs, based on the environmental consideration is also discussed.","PeriodicalId":339120,"journal":{"name":"2016 First International Conference on Sustainable Green Buildings and Communities (SGBC)","volume":"59 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134624199","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
