Also the control approach offers the possibility of operating the FB-MMC from bi-polar dc link voltages; thus, creating new possibilities for building generic hybrid dc grids with reversible dc link voltage, where conventional line commutated current source converters can operate in conjunction with voltage source converters. Additionally the control approach improves dc fault ride-through of the FB-MMC compared with existing approaches. This is achieved by active control of the arm currents and cell capacitor voltages, and exploitation of the FB-MMC redundant switch states. FB-MMC operation with reversible DC link voltage and decoupled control of the cell capacitor voltages from the dc link voltage are demonstrated using simulations.","PeriodicalId":231255,"journal":{"name":"2015 IEEE Electrical Power and Energy Conference (EPEC)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-10-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130492226","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}

Importantly, the corresponding power losses should be accurately calculated in order to reach performance targets (very high efficiency). This paper reviews the most known analytical models which are used to calculate the medium frequency resistance for several winding technologies. In order to qualify these models in a future design flow, we compare the analytical model results with measurements and 3D finite element (3DFE) electromagnetic simulations. The adopted design flow-chart has been tested on a 17 kHz - 180 kVA prototype transformer that will be used in a Dual Active Bridge (DAB).","PeriodicalId":231255,"journal":{"name":"2015 IEEE Electrical Power and Energy Conference (EPEC)","volume":"9 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-10-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121844814","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 framework is flexible with regard to the choice of optimization algorithm, constraints, choice of parameters, variants of the ITM path-loss model and terrain generation.

The single diode model of a PV module requires estimation of 5 unknown parameters derived from the equivalent circuit using only the parameters extracted from datasheets as input. These parameters are used to evaluate the current and voltage from the module under varying conditions of temperature and irradiance. This paper presents the Gauss-Seidel method in a step by step manner to extract the 5 unknown STC parameters used in a single diode PV model with series and shunt resistances. These parameters are then used to plot the I-V characteristics of two PV modules, SQ80 and the GEPV110 under varying temperature and irradiance. Algorithm of the Matlab code used for implementation of the model is presented. The results are then verified by simulations using graphs extracted from the datasheet of the GEPV110 as well as plots from experimentally measured values for the SQ80 PV module.","PeriodicalId":231255,"journal":{"name":"2015 IEEE Electrical Power and Energy Conference (EPEC)","volume":"42 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122951620","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}

A control method utilizing the duty-cycle of two half-bridge circuits and the phase-shift between them is proposed.

However, integrating wind energy with the grid tends to reduce the reliability of the system due to the intermittency of the wind. Direct load control (DLC) is one solution to balance consumption with generation. Domestic electric water heaters (DEWHs) are feasible candidate for this purpose because they hold a large share of the aggregated load and follow a similar daily profile. This paper presents a novel load control strategy based on load forecast which provides an estimation on the ramp-up/down reserve capacity. The proposed controller was deployed on a pilot project called PowerShift Atlantic. This project is lead by Canadian Maritime utilities that demonstrates direct load control strategies to provide up to 20MW of ancillary services by controlling various load classes. This paper presents the control strategy implemented in this system along with the experimental results.","PeriodicalId":231255,"journal":{"name":"2015 IEEE Electrical Power and Energy Conference (EPEC)","volume":"10 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129356484","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}

To comply with this new Reliability Standard, several aspects of transient stability study need to be enhanced: (1) selection of study cases, and of contingencies potentially causing reliability violations or producing more severe system impacts including cascading; (2) inclusion of actual actions of protection systems and SPS; (3) automation of procedure to identify transient stability violations based on the established criteria; and (4) mechanism for identifying and simulating cascading.","PeriodicalId":231255,"journal":{"name":"2015 IEEE Electrical Power and Energy Conference (EPEC)","volume":"197 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134461846","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}

There is a steady increase in the electrical energy being fed from renewable energy sources like wind and photovoltaic systems while shutting down large thermal power plants. This trend has a major impact on the performance of the electrical power system networks especially with respect to their dynamic behaviour. Phasing out of existing conventional synchronous generators will adversely affect auxiliary services like voltage control and frequency regulation. The paper discusses one of the solutions to cope with these challenges: the use of Modular Multilevel Converter based STATCOM i.e. SVC PLUS® with power intensive energy storage (SVC PLUS ES) which can significantly contribute to the stable operation of the power system. The successful frequency and voltage support in transmission grids will be presented.

In such a noisy channel, the performance of a Zigbee-based WSN network is simulated using the NS-2 network simulator.
