In fact, the high penetrations of RER and PEVs have increased the importance of impact assessment involving system protection. A framework is presented in this paper for modeling the combined operations of RER based solar Photovoltaic (PV) systems and PEVs in a microgrid integrated with power grid. The paper also proposes a fault current limiter connected in parallel (anti-islanding protection) with the circuit breaker in the point of common coupling (PCC), thus providing current bypass circuit during abnormal conditions. The concept of the proposed scheme is validated under various operating conditions using a 24-hourly dynamic simulation. The results demonstrate the effectiveness of the proposed approach.","PeriodicalId":404327,"journal":{"name":"2017 IEEE International Conference on Smart Energy Grid Engineering (SEGE)","volume":"38 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-09-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129178811","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}

System-wide analysis of the flexibility potential of TES necessitates representation of dynamic thermal models in large-scale power systems models. Therefore, this study presents a novel Building-to-Grid (B2G) model integrating buildings' thermal dynamics and end-use constraints with a security-constrained unit commitment model for energy and reserve scheduling. The behaviour of residential thermal demand is represented through linear state space (RC-equivalent) models for different residential archetypes. The B2G model is subsequently used to evaluate the energy arbitrage and reserve provision potential of TES for a test system and various sensitivity analyses for wind penetration levels and presence of other flexibility options have been conducted. The optimisation results highlight the significant value of TES in terms of annual generation cost savings, reserve provision, peak load reduction and utilization of wind energy. The findings also emphasize the importance of co-optimising energy arbitrage and reserve provision from TES devices vis-a-vis system performance and household energy consumption scheduling.","PeriodicalId":404327,"journal":{"name":"2017 IEEE International Conference on Smart Energy Grid Engineering (SEGE)","volume":"28 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-08-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133878991","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 operation of the power filter/compensator device is based on the intermittent switching between a double tuned filter and a series compensator. The switching process is achieved by a pulse signal generated from pulse-width modulation switching. The PID controller which is used to modulate the pulse-width modulation is driven by an error signal generated from a dual loop traditional controller. The Matlab/Simulink software environment is used as a simulation tool. The results show that the power filter/compensator device enhances the power factor and improves the voltage profile at the system buses. Also the power filter/compensator device has a great effect on the mitigation of harmonic distortions of the voltage at the system buses that is downstream it while the enhancement of the harmonic distortions is in the current waveforms at the system buses upstream it.","PeriodicalId":404327,"journal":{"name":"2017 IEEE International Conference on Smart Energy Grid Engineering (SEGE)","volume":"2 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125371133","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}

Different energy recovery technologies such as pyrolysis, incineration, gasification, etc. can be applied to manage plastic wastes properly. This leads to use of renewable resources instead of fossil fuels and consequently decreasing greenhouse gas emissions.

The process of delivering energy is production, transmission and distribution; we focus on distribution process in this paper because in default transmission or in outage case we have to response to majority of demand in the islanded region during outage. The problem is to how optimize energy distribution and distribute smartly the exiting energy produced or stored in the local region with integration of prosumers for an efficient power management. We propose in this paper a smart approach for an advanced balancing of powers based on dynamic selection algorithm to collect real time information and select entities that will be powered. The selection is based on some parameters like geographic position, obligatory load, optional load, level of priority, and local self-production if exist. The selection is dynamic because parameters can be changed and the information is detected by controller installed in each entity all connected to the regional data center to analyze and make decisions to manage and improve reliability of power supply by supplying load during power outage. As result of emergency strategy we obtain a smart outage distribution network for the intentional islanding. An intelligent algorithm is developed as proposition of solution to the problem with discussion results of the distribution model simulation.","PeriodicalId":404327,"journal":{"name":"2017 IEEE International Conference on Smart Energy Grid Engineering (SEGE)","volume":"21 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126445503","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 advantage of microgrid lies in its capability to work in stand-alone (island) and grid-connected mode. During the transition from grid-connected mode to island mode, there is a possibility of large voltage and frequency deviations, which is undesirable for the local loads connected to the system. These variations also build up stress on the power converter components associated with the circuitry of each of the micro-source. During the transition from stand-alone mode to grid, connected mode there is large probability of voltage and current transients. To avoid such situations, seamless mode transfer between the two working modes, an appropriate control scheme should be devised. This paper presents a control scheme wherein the micro-source inverter works in voltage control mode amid stand-alone operation and in current control mode amid grid-connected operation and switches over easily between these modes during the transition phase. The exhibited control scheme is simulated with MATLAB/Simulink and the obtained results are confirmed with hardware implementation utilizing Texas Instruments digital signal processor TMS320F28069. Simulation and hardware results establish the accomplishment of the proposed control strategy for seamless mode transfer in the microgrid.","PeriodicalId":404327,"journal":{"name":"2017 IEEE International Conference on Smart Energy Grid Engineering (SEGE)","volume":"9 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115790905","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}
