The proposed method can track the power system dynamics by periodically updating the sensitivities to the unobservable buses during the intervals between successive outputs of state estimator with SCADA measurements. The performance of the proposed method is evaluated on a number of standard test systems for different sets of un-observability. Simulation result shows that the proposed method can track the electromechanical dynamics of the system during the large disturbances in the system, it also improves the accuracy of the estimates and enhances the numerical stability of the estimation.","PeriodicalId":444960,"journal":{"name":"2014 IEEE Innovative Smart Grid Technologies - Asia (ISGT ASIA)","volume":"13 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-05-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130876496","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}

In this paper the effect on secondary reserve necessary to overcome the added uncertainty is analyzed. Maximum wind power demand coverage, limited by the secondary reserve value requirement, is assessed. The Spanish power system is used for numerical application using real data. Maximum demand coverage of around 60%-80% is possible without compromising secondary reserve value. An increase of 70%-200% in secondary reserve is expected for a demand coverage of around 60%. Some dynamic performance considerations on the secondary regulation are given for the Spanish case.","PeriodicalId":444960,"journal":{"name":"2014 IEEE Innovative Smart Grid Technologies - Asia (ISGT ASIA)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-05-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129138545","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}

Existing lighting systems are clock-oriented and offer limited monitoring and control capabilities. The proposed system automatically adjusts the illumination level of individual lamps according to the ambient lighting conditions and occupancy pattern of the surrounding; it is also adaptable to regions (or) different time-zones by itself. The inter-lamp communication over the master-slave network facilitates an efficient lighting system beyond individual lamp fixtures. Remote monitoring helps in condition monitoring while remote control enables easy user interference. The proposed system will result in lower maintenance cost, higher energy savings and eventually leads to a faster return-on-investment of the system. In this paper, a prototype of the system is presented and its feasibility is demonstrated.","PeriodicalId":444960,"journal":{"name":"2014 IEEE Innovative Smart Grid Technologies - Asia (ISGT ASIA)","volume":"178 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-05-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114563791","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}

Hence extensive efficiency reduction can occur, especially with use of field-conducting materials, such as ferrites. This has an impact on the frequencies of the sending and the receiving resonant circuit according to the calibration condition. Based on measurement and simulations of the inductance of the coils analyses to investigate the performance of the resonant system are done. It ends with the depiction of possible solutions. As a first step to set up the equivalent circuit diagram (ECD) all components must be defined. Therefore the compensation strategies are presented and analyzed in detail. This has a great influence on the adjusting resonance frequencies at different positional tolerances. All simulations and calculations are done with Simplorer (Ansys)1, respectively Maple2 (Maplesoft) to get a qualitative indication for system performance.","PeriodicalId":444960,"journal":{"name":"2014 IEEE Innovative Smart Grid Technologies - Asia (ISGT ASIA)","volume":"111 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-05-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129203052","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}

Energy market in residential sector is rapidly growing due to highly penetrated PV. It requires safety, reliability, economic efficiency, environment-friendly and fair control. Our target is to develop the energy management system (EMS) satisfying previous requirements. In this paper, load aggregator's targets are to decrease peak-to-peak interconnection point power flow and achieving harmonized battery energy storage system (BESS) control. Load aggregator makes SOC schedule and interconnection point power flow bandwidth based on hourly forecasting data in a day ahead. On the day, BESSs are minutely controlled to decrease excess power flow compare to the scheduled power flow bandwidth based on SOC schedule. Simulation results show reduction of the peak-to-peak interconnection point power flow and power fluctuation due to smoothing effect and discuss about fairness of the BESS control.","PeriodicalId":444960,"journal":{"name":"2014 IEEE Innovative Smart Grid Technologies - Asia (ISGT ASIA)","volume":"29 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-05-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132110208","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}

Through mathematical description of the appliance operation, a suitable work plan timtable for the electric appliances is derived to satisfy both the power limits requested from the power suppliers and the least cost expectation from user side. Furthermore, the utility suppliers will monitor the behaviours of the energy requirement from the customers. When the demanded power is too high, a feedback signal will be sent to ask the customers to stop using some kinds of appliances or delay their operation for a while. When the demand power is too low, a signal will also be sent to the end users to remind that some flexible appliances can be activated in order to achieve the load shifting effect.

Thus, short-term load forecasting has to be provided at the distribution level. Most of loads forecasting algorithms are based on bottom-up approach, consisting in years' worth of endusers consumption data, related together by an interpolation function. This paper presents a new top-down algorithm, based on a Similar Day Type method, and allows to compute an accurate short term distribution loads forecast using only SCADA Data from transmission grid substations. This algorithm is evaluated on the RBTS test system with real power consumption data to demonstrate its accuracy. This fast, robust and automatic method does not require years' worth of data nor any consumption data at the end-users level, but only power flow data from primary substations, which makes it implementable rapidly, at a lower cost, and on every grid.","PeriodicalId":444960,"journal":{"name":"2014 IEEE Innovative Smart Grid Technologies - Asia (ISGT ASIA)","volume":"106 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-05-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123445636","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 control information is delay sensitive and requires a reliable communication. Hence, it is necessary to select the best communication technology from the available candidates to satisfy the high Quality of Service (QoS) requirement of control information. Among various applications involved in a smart grid network, providing solution to control non-technical losses including electrical theft is one of the most serious problems in developing countries. Therefore, this paper discusses the suitable communication networks and proposes a framework to control non-technical losses in energy distribution systems. The non-technical losses in customer premises like tampering of electrical devices are conveyed, whereas an unauthorized theft in overhead lines is computed at the control center. Then, the control center identifies the electrical theft in a particular segment of the feeder and tries to identify the exact location using unmanned aerial vehicle (UAV). Finally, the control center finds the nearest staff personnel using Global Positioning Systems (GPS) and conveys power loss and theft details using General Packet Radio Service (GPRS) network to control the electrical theft.","PeriodicalId":444960,"journal":{"name":"2014 IEEE Innovative Smart Grid Technologies - Asia (ISGT ASIA)","volume":"6 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-05-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121245739","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}
