This paper provides a graphical method with high-order derivatives of voltage phase angle dynamics for transient stability analysis. Using a Single Machine Infinite Bus system, criteria are defined for determining unstable equilibrium points using the first, second, and third order derivatives of phase angle difference. To intuitively show stability characteristics, a new phase plane is defined with the first and second order derivatives. With measurement data from phasor measurement units, bus voltage phase angle and frequency dynamics are used for field application. Applications of the proposed method for transient stability evaluation and prediction are discussed. Simulations show that the proposed method provides an intuitive approach for transient stability analysis and is useful in field applications.","PeriodicalId":161074,"journal":{"name":"2014 IEEE PES T&D Conference and Exposition","volume":"25 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-04-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125606045","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}

One of the difficulties that hindered the growth of a competitive power market is the absence of efficient computational tools to assist the design, analysis and operation of the power market. Although many commercial software packages have been developed for a broad study of an electric power system, these power system simulators are usually not designed in such a way that can be used for analysis and evaluation of an agent-based competitive power market. This paper investigates mathematical models associated with a competitive power market and how these models can be converted in such a way that makes it possible to use commercial power system software for agent-based modeling and simulation of a competitive power market. The paper also develops a mechanism to integrate PowerWorld and MatLab for combined optimal power dispatch and agent-based learning interactions. Finally, the paper demonstrates a case study for a competitive electric power system using the integrated software system.","PeriodicalId":161074,"journal":{"name":"2014 IEEE PES T&D Conference and Exposition","volume":"22 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-04-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126726640","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 joint transmission expansion planning and energy storage placement is proposed to satisfy the requirements of a power system model with wind farm generation. The problem is formulated as a multistage mixed integer programming problem, aiming to minimize the total investment and operational costs incurred for integrating wind generation. The operating cost captures the benefits subject to the planning decisions. Based on the DC power flow model, the optimal planning is presented, which strikes a balance between the system expansion cost and the operational cost. By leveraging the properties of the proposed optimization problem, the formulated problem is transformed into a linear mixed integer program. Numerical studies, using the modified Roy Billinton Test System (RBTS) and IEEE Reliability Test System (RTS), explore the proposed optimization method and compare the central and distributed energy storage schemes. The results demonstrate the significant benefits of the proposed approach.","PeriodicalId":161074,"journal":{"name":"2014 IEEE PES T&D Conference and Exposition","volume":"717 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-04-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122993825","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 will present a novel scheme that provides significant benefit to operators of rural overhead MV distribution networks in terms of reliability improvement and minimizing the risk of electrical faults causing ignition of wild fires. Firstly, the key criteria for reliability optimization and mitigation of electrical faults causing ignition of fires are presented. An assessment of the performance of a number of typical lateral line protection schemes is conducted. All traditional approaches have a number of deficiencies, primarily related to preventing wild fires. New ultra-fast circuit breaker technology is introduced that enables a new approach to the optimal protection of rural lateral lines. A novel protection scheme is presented and is shown to represent the optimal solution for both reliability performance and prevention of electrical faults causing wild fire ignition on extreme weather days. For fault levels typical on rural lateral lines, when switched off in less than a half cycle, there is inadequate energy in the arc to cause fire ignition. This alternate protection mode can be remotely commanded over SCADA to allow rapid network response to extreme weather. An example is presented to clarify the expected performance.","PeriodicalId":161074,"journal":{"name":"2014 IEEE PES T&D Conference and Exposition","volume":"87 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-04-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121176261","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}

Direct load control (DLC), a strategy of autonomous demand response, has been applied to mitigate operational burdens on generation units for frequency regulation. Variable speed heat pumps (VSHPs) have been regarded as promising devices that can respond to the DLC signal updated every 2 or 4 seconds. This paper presents a dynamic model of the VSHP that is simplified for real-time simulation studies but still sufficiently comprehensive to analyze its physical and operational characteristics. Furthermore, a variable speed drive (VSD)-controlled induction motor model is designed together with an indirect torque controller for the adjustment of the VSHP input power. In addition, based on experimental setup and data, a test room was modeled to estimate the effect of the DLC-enabled VSHP on indoor temperature. Simulation case studies performed in Matlab/Simulink verify that the VSHP can be well utilized as DLC-enabled loads for frequency regulation while ensuring residents' comfort and long-term device performance.","PeriodicalId":161074,"journal":{"name":"2014 IEEE PES T&D Conference and Exposition","volume":"31 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-04-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123835968","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}

By using the measured voltage, as an input to the model, the response of the model is computed and compared with the measured response of the shunt dynamic device. An optimization algorithm is used to optimally estimate the gains of the modeled controls in order to achieve good agreement between the simulated and measured response of the device.

It is shown how the EVRs can reduce the rapid voltage change level of distributed generation (DG) on weak networks and increase the amount of generation that can be connected to the network. EVRs improve power quality by limiting the voltage variations caused by highly variable generation such as the power produced by photo-voltaic (PV) plants. Simulations are performed on a test network to compare the penetration levels of different DG connection cases. It is shown that the EVRs have the potential to increase DG penetration levels substantially while improving power quality at the same time.","PeriodicalId":161074,"journal":{"name":"2014 IEEE PES T&D Conference and Exposition","volume":"5 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-04-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131097847","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}
