During normal operation the SCESS will be used to minimize the short term fluctuation as it has high power density and during fault at the grid side it will be used to store the generated power from the PV array for later use and for fault ride through. To capture the maximum available solar power, Incremental Conductance (IC) method is used for maximum power point tracking (MPPT). An independent P-Q control is implemented to transfer the generated power to the grid using a Voltage source inverter (VSI). The SCESS is connected to the system using a bi-directional buck boost converter. The system model has been developed that consists of PV module, buck converter for MPPT, buck-boost converter to connect the SCESS to the DC link. Three independent controllers are implemented for each power electronics block. The effectiveness of the proposed controller is examined on Real Time Digital Simulator (RTDS) and the results verify the superiority of the proposed approach.","PeriodicalId":395633,"journal":{"name":"2014 Saudi Arabia Smart Grid Conference (SASG)","volume":"198 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124277785","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 paper demonstrates results from voltage stability studies carried out in PSSE using dynamic load models showing the voltage recovery without and with an SVC application in the National Grid. A Real Time Digital Simulator (RTDS) was used for performance verification of the SVC in real-time, considering a representation of the grid external to the SVC and integrating the MACH 2 control hardware of the SVC into the simulation loop. Consistent results from PSSE and RTDS simulations have been obtained.","PeriodicalId":395633,"journal":{"name":"2014 Saudi Arabia Smart Grid Conference (SASG)","volume":"15 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121842149","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 main circuit configuration and models of the devices are introduced in the work. The paper proposes a control scheme to increase the system damping and improve the system response; then employs Differential Evolution (DE) optimization algorithm for optimal tuning of the proposed controller. Nonlinear time domain simulation based on multi-objective function is formulated to minimize the time-weighted errors in order to damp the system oscillations, which are inherent in the nonlinear system model. An interconnected power system equipped with both devices, one at a time, is discussed in this paper. The system response is examined under different disturbances. The results are presented and compared. The results show increased damping of low frequency oscillations with STATCOM as compared to SVC.","PeriodicalId":395633,"journal":{"name":"2014 Saudi Arabia Smart Grid Conference (SASG)","volume":"4 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133113646","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}

While these savings have typically been achieved through the application of complex power-flow models, this approach is not well suited to the modern grid (e.g. distributed energy resources, etc.). New technology has been introduced to the market that allows the benefits of CVR to be achieved without the constraints of traditional approaches. This paper will present this unique signal processing and control technology and the benefits that have been achieved using this technology in North America, and will provide insight into an application in Saudi Arabia being conducted with Saudi Aramco.","PeriodicalId":395633,"journal":{"name":"2014 Saudi Arabia Smart Grid Conference (SASG)","volume":"617 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116077100","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 devastating episode of open burning started in the year 1997 in Indonesia which deeply affected most of the ASEAN countries especially their neighbour Malaysia and Singapore. The Photovoltaic (PV) technology as an alternative means of energy generation experiences such significant energy decrease based on this condition which is due to the shading of sunlight. The six hours claims of good sunlight has become not more than 2 hours and gets worst when the Air Pollution Index (API) struck 200 levels which is at very unhealthy condition. This study embraces some findings from 1 kWp PV generator field data installed in Malaysia reflecting the daily energy decrease operated during this unhealthy weather condition. It is found that such significant energy decrease with the value of 0.43 W power output per increment of 1 point API. This value shows such concrete proof of additional factors to be considered in PV modelling in line to support PV technology adaptation in the Asean region.","PeriodicalId":395633,"journal":{"name":"2014 Saudi Arabia Smart Grid Conference (SASG)","volume":"17 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128071585","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}
