Whenever a city network is disconnected from the distribution grid, a blackout occurs and local producers are disabled. Micro grids circumvent blackouts by leveraging these local producers to power a fixed subset of consumers. In this paper, we evolve micro grids to Holons, which overcome the need for fixed subsets and power as much of the city network as possible. We contribute a formal model of Holons and investigate the impact of the Holon concept in a simulation with 10,000 randomly generated city networks. These city networks are based on parameters obtained from a real-world test site in a medium-sized German city. Our results show that the Holon approach can supply an average fraction of 22.08% of any city network, even when fixed micro grids would fail to power the city network as a whole.","PeriodicalId":448232,"journal":{"name":"2016 5th International Conference on Smart Cities and Green ICT Systems (SMARTGREENS)","volume":"68 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-04-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116037476","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 existing nonlinear solvers often fail in yielding a feasible solution. In this paper, we follow our previously developed nonsmooth optimization approach to address this difficult large-scale OPF problem, which is an iterative process to generate a sequence of improved solutions that converge to an optimal solution. Each iteration calls an SDP of a moderate dimension. Intensive simulations for OPF over networks with a large number of buses are provided to demonstrate the efficiency of our approach.","PeriodicalId":448232,"journal":{"name":"2016 5th International Conference on Smart Cities and Green ICT Systems (SMARTGREENS)","volume":"2 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-04-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124954937","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 specialized automatic system maintains constant the indoor temperature when the heat input in building equals the heat loss through the building envelope. The specialized automatic system consists of several subsystems. The model for each subsystem is obtained considering the particularities of the heating processes from buildings and requirements for the thermal comfort. By simulating the operation of the specialized automatic system is obtained the time behavior for the main physical values that characterizes the system,_relevant to the quality of the heating temperature control in the building. The operation of the automatic controller and the control valve are analyzed by simulation, in a comparable time interval with transient regime of the automatic heating system of the real building. The validation of the model is done by comparing the results obtained by simulation with results of experimental measurements in the real automatic system, implemented in the building chosen for study.","PeriodicalId":448232,"journal":{"name":"2016 5th International Conference on Smart Cities and Green ICT Systems (SMARTGREENS)","volume":"3 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-04-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116071564","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 Smart Grid paradigm introduces new possibilities of real-time market sensing and interaction models between producers and consumers. In particular, by understanding the types of consumers and their potential willingness to adapt their energy demand with price incentives, innovative pricing strategies in the Smart Grid are expected to lead to better production management, profit maximization and end consumers satisfaction levels.
