In this system, the small-hydro works in V/f control mode, the PV and battery storage systems work in P/Q control mode to make full use of solar energy and reduce the amount of water and diesel used.

Although, it is important to identify and quantify the individual uncertainties of the measurement chain components and consequently the combined measurement chain uncertainty, it is nearly impossible to do this for all the components. In this paper a simplified measurement chain is considered that consists of the instrument transformer and the measurement device. The importance of considering the accuracy class of the instrument transformer is underlined by examining the effect of the instrument transformer accuracy class on the performance of a conventional and a hybrid state estimator performance.

Through government driven demand side management programs, policies have been developed that generally encourage the development of customer centered microgrids. Some of the incentives offered to energy users include provision of cash rebates for installation of wind turbines, availing free or subsidized photovoltaic (PV) panels to customers and through offering renewable energy credits to the consumers. These microgrids are connected to the main utility grid where there is a two way exchange of power. However, proper mechanisms must be put in place to regulate the interaction between the main grid and the microgrids. Among the critical issues that need to be addressed include the amount of renewable power that can be fed to the main grid as well as the energy price at which this is done. This paper therefore presents the demand side energy management for a grid connected household with a locally generated photovoltaic energy.","PeriodicalId":433870,"journal":{"name":"2013 IEEE Power & Energy Society General Meeting","volume":"347 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-07-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126030051","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 ZigBee wireless platform is a cost-efficient wireless networking system recently for the purpose of monitoring substation components in electric substations. Although this system has some inherent resistance to interference given its spread spectrum technology, impulsive noise with a short duration and a strong energy content caused by partial discharge (PD) of a dielectric breakdown can degrade the communication quality of ZigBee nodes. In this paper, a novel statistical model of substation PD impulsive noise is proposed and the impact of this impulsive noise on the ZigBee 2.4 GHz and 915 MHz frequency bands is evaluated. Although our results show the 2.4 GHz ZigBee is more resistant to PD impulsive noise in electricity substations, it may be advantageous to deploy 915 MHz ZigBee if PD detection and concurrent telemetry data collection are desired.","PeriodicalId":433870,"journal":{"name":"2013 IEEE Power & Energy Society General Meeting","volume":"50 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-07-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125491000","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}

Communication performance parameters like delay and loss in transfer of measurements and commands can affect the result of control and should be taken into account while studying a control mechanism over power system dynamics. In this paper we present the method and tools that we have developed to allow simulation of communication networks inside off-the-shelf product for power system transient simulation, PSCAD. In particular we present the structural designs and interfaces of modules that are needed for implementing an embedded communication network simulator in PSCAD, and provide a brief guide on how power system engineers could use these modules in their designs. In addition, we present an example of a control scheme using communication for stabilizing a power system that incorporates integration of a renewable energy source and energy storage. We use the IEEE 13-node test feeder as our case study. A wind generator and battery are connected to the system to add more dynamic behavior; a control for the system has been designed which works with communication interface and modules implemented in PSCAD. The test system is used to validate and verify the embedded communication simulator and its implementation.","PeriodicalId":433870,"journal":{"name":"2013 IEEE Power & Energy Society General Meeting","volume":"19 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-07-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125536251","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}

New technologies like Micro Combined Heat and Power Plants (μCHPs), heat pumps or photovoltaic systems are connected to the low (LV) and medium voltage (MV) level.

To evaluate the influence of these devices to the system a test environment was designed in which μCHPs could be tested. The environment enables the emulation of grid-connected and islanded mode of operation with a power system emulator under consideration of thermal loads. In this paper the electrical power system and thermal network emulator are described in detail. In a first step the corresponding research project is explained and following the working principle and the key facts of the Combined Energy Lab (CEL) are shown.
