This paper focuses on the secondary control level, which can be classified as centralized or decentralized control. A comprehensive investigation of both centralized and decentralized control is presented in this paper. Decentralized control is proposed in order to deal with some of the disadvantages of central control, such as the high risk of unplanned interruption arising from a Microgrid Central Controller (MGCC) malfunction. However, decentralized control is not yet complete, and some challenges to its implementation remain. This paper also looks at these challenges and proposes some solutions that may help to improve the performance of decentralized control and overcome its disadvantages. Finally, a general methodology of microgrid control is modeled.","PeriodicalId":408526,"journal":{"name":"2015 International Conference on Smart Cities and Green ICT Systems (SMARTGREENS)","volume":"69 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-05-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129283670","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}

The paper tackles the study of feasibility to implement fuzzy logic control into an energetic hybrid system and to optimize the membership functions of the fuzzy logic controller for the Photovoltaic-Proton Exchange Membrane Fuel Cell hybrid system using genetic algorithm (GA). The paper deals with a fuzzy logic control strategy objective to produce electrical energy according to the demand, prone to the constraints and the dynamics of the physical load and intermittence of the energetic resource, by distributing the energy demand between the photovoltaic field and the Proton Exchange Membrane Fuel Cell system. Photovoltaic-Proton Exchange Membrane Fuel Cell is described in detail as well as system configuration and components' parameters. The second section devotes to demonstrating the design process of fuzzy logic control for Photovoltaic-Proton Exchange Membrane Fuel Cell hybrid System. Finally, the optimal control problem is addressed and genetic algorithm is introduced to help find a set of optimum parameters in the fuzzy logic controller, best results are obtained and good optimization of the hybrid system is highlighted.","PeriodicalId":408526,"journal":{"name":"2015 International Conference on Smart Cities and Green ICT Systems (SMARTGREENS)","volume":"34 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-05-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133148578","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}

Each heat pump provides space heating and domestic hot water to a single household. Besides a heat pump, each house has a buffer for domestic hot water and a floor heating system for space heating. The paper describes models and algorithms used for the prediction and planning steps in order to obtain a planning for the heat pumps. The optimization algorithm minimizes the maximum peak electricity demand of the district. Simulated results demonstrate the resulting aggregated electricity demand, the obtained thermal comfort and the state of charge of the domestic hot water storage for an example house. Our results show that a model predictive control outperforms conventional control of individual heat pumps based on feedback control principles.","PeriodicalId":408526,"journal":{"name":"2015 International Conference on Smart Cities and Green ICT Systems (SMARTGREENS)","volume":"84 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-05-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116045970","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}

Identifying unusual operating behavior, detecting device failures in advance, and recognizing energy saving potentials are key features to improve the reliability, safety, and profitability of those systems. Facing these tasks, todays research is focused inter alia on a non-intrusive load monitoring approach, where the electrical signal is measured at a central point with modern hardware and processed by pattern recognition algorithms. Thus, we developed a smart meter prototype with a high sampling frequency, which allows for continuous measurement of the current and voltage from three-phase power lines. Besides this, in this paper we describe the usage of current-only measurement data (simple and safe installation using current transformers) with which we were able to classify state changes of a mobile air-conditioner with the help of Fourier descriptors as well as with additional voltage measurement.","PeriodicalId":408526,"journal":{"name":"2015 International Conference on Smart Cities and Green ICT Systems (SMARTGREENS)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-05-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116054418","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 bottom-up approach method has been selected to arrive at the potential as this gives a better estimate than a top-down approach. The novelty of the study lies in estimating the potential at high resolution and classifying the rooftop as suitable or not for solar photovoltaic installations based on factors like irradiation, slope and orientation. The city of Apeldoorn in the Netherlands has been selected as the study area. The model was able to successfully locate suitable sites for photovoltaic installations at rooftop level. In addition, the area feasible for the installations and the potential power output has also been calculated. We conclude that the city has a potential of 319 MWp capacity, which would yield 283.9 GWh/yr in relation to the 304 GWh/yr consumption from residential buildings in the area.","PeriodicalId":408526,"journal":{"name":"2015 International Conference on Smart Cities and Green ICT Systems (SMARTGREENS)","volume":"305 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-05-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124223469","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}

Coupling various energy sectors can offer many benefits in the way of flexibility and better utilisation of resources and infrastructures. To illustrate the benefits of coupling the heat and electricity sectors, a general model for a domestic energy system is developed, and two simulations are performed of domestic systems with sector coupling technologies. Further benefits can be gained by optimising the two systems together, implying that it can be advantageous to take an integrated optimisation approach for larger numbers of domestic systems.","PeriodicalId":408526,"journal":{"name":"2015 International Conference on Smart Cities and Green ICT Systems (SMARTGREENS)","volume":"19 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-05-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127851406","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}
