The goal is to 1) reduce the total real and reactive power losses, 2) improve the voltage profile, and 3) improve the power factor for the total demand. The method uses a bus-ranking scheme based on a weighted sum of indices representative of the impacts that a DG unit or capacitor bank would have in terms of the three aforementioned objectives. Moreover, the introduced indices provide a quantitative measure to identify whether placing a DG unit or a capacitor bank is more beneficial at each bus. In order to assess the performance of the proposed method, a 49-bus distribution system is introduced. The method is applied on the test system and best locations for allocation of DG units and capacitor banks on each branch are identified. Besides, a comparison between the performance of DG units and capacitor banks at each bus is noted. At the end, by examining the resulting real and reactive power losses, voltage profile and power factor, it is demonstrated that the proposed method successfully accomplishes its objectives.","PeriodicalId":249041,"journal":{"name":"2016 North American Power Symposium (NAPS)","volume":"43 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131601862","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}

Because of this, wind farm technologies will influence the power system behavior modifying its dynamics by reducing power systems global inertia. Hence, there is an increased interest and need to study the wind turbine farms behavior and their effects on the power system not only by researchers but also from transmission system operators. This paper describes the current modeling and aggregation methods for wind farms. Following a discussion of the different aggregation methods, including full aggregated model, semi aggregated model and multi machine model, an evaluation has been done to study the performance of each method in providing the entire response of the wind farm at the interconnection point with the grid under real wind speed profile and fault condition. Finally, the needs for further research and the challenges in the concept of wind farm dynamics and aggregation have been discussed.","PeriodicalId":249041,"journal":{"name":"2016 North American Power Symposium (NAPS)","volume":"3 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128018350","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 order to have a reliable and secure operation condition, it is desirable to include the AC networks constraints and the system's stability indices into the day-ahead generating scheduling problem of power systems. However, including such a non-convex set of constraints in the problem formulation, the complexity and size of the SCUC problem would increase; thus, the convexity of the mathematics model and the computational burden of the SCUC problem increases significantly. To avoid this issue, in this paper, we present a decentralized solution methodology where the voltage stability constrained SCUC (VSC-SCUC) problem is divided into multiple smaller subproblems; then, using the auxiliary problem principle (APP), the operating points of the subproblems are coordinated with each other iteratively in a parallel manner. In order to justify the effectiveness of the proposed method, several case studies are presented and discussed.","PeriodicalId":249041,"journal":{"name":"2016 North American Power Symposium (NAPS)","volume":"27 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131871252","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 formation of zones depends on a set threshold, connectivity and type of pricing mechanism. In this paper, a novel concept to club the nodes into zones that are closely connected and experience similar usage prices, for few of the popular transmission pricing mechanism such as equivalent bilateral exchange (EBE), marginal participation method (MPM) and hybrid method (HM), is proposed. A concept of edge betweenness is utilized for this purpose. Also, a quality index as a function of edge weight is proposed to make decision for optimal number of zones.

Since frequency deviation is strongly affected by inertia, a minimum amount of inertia is vital to maintaining frequency stability. The generation dispatch problem not only finds a solution for generation that minimizes cost and emission but also one that ensures system stability. This paper addresses the environmental-economic generation dispatch of a power system while considering frequency stability in the optimization problem. The proposed frequency stability constraint is represented by the maximum system frequency deviation limit. A non-dominated sorting genetic algorithm II is implemented to investigate the multi-objective dispatch problem. Environmental-economic generation dispatch will be examined on the IEEE 30-bus system to demonstrate the proposed idea.","PeriodicalId":249041,"journal":{"name":"2016 North American Power Symposium (NAPS)","volume":"34 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115217286","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 discusses the impact of PMU measurement errors and limitations originated from hardware implementation of various phasor estimation algorithms on the accuracy of the synchrophasor-based fault location application, in particular on the fault location algorithm that uses synchronized phasors at both line terminals. The application test procedure is implemented on a simple two-bus system modeled in ATP-EMTP with different types of fault scenarios simulated and various real PMUs exposed to the fault signals through hardware-in-the-loop testing.

Key to this end is to consider a nonlinear dynamical system with non-incremental local Volt/VAr control, cast the Volt/VAr dynamics as a game, and leverage the fixed-point theorem as well as pertinent contraction mapping argument.

In line with this research, numerous feasibility studies have also been performed to examine better ways to drive competitive and affordable pricing within the design, development, testing and evaluation (DDTE) of remote/backup power generation stations. This paper draws from prior research on small scale HI-RES and further explores the analytical data and conclusions attained from other independent case studies performed across the globe.
