The rapid expansion of photovoltaic systems within the last years poses a growing problem especially for grid operators. New innovative concepts like smart storage solutions for reducing the grid load often need a generation forecast in order to be operated properly. In this work, a photovoltaic forecast based on only freely available cloud data is developed and compared to a commercially available one by evaluating their accuracy. Therefore, both forecasts are adapted to a 14 kWp photovoltaic system in Upper Bavaria, Germany. An Analysis of the results shows that both forecasts yield comparable results, but the one based on freely available data shows extreme inaccuracies in case of difficult prediction conditions like changeable cloud movement.","PeriodicalId":6497,"journal":{"name":"2016 IEEE/PES Transmission and Distribution Conference and Exposition (T&D)","volume":"22 1","pages":"1-5"},"PeriodicalIF":0.0,"publicationDate":"2016-05-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"87275044","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}

Although attractive from the reliability and economic standpoint, the attention must be paid to the impact on the power system operating states following the switching implementation to make sure the system security performance in the new migrated operating state is not jeopardized. This paper suggests a probabilistic measure to foresee the likelihood of experiencing undesirable operating state following execution of an optimal hour-ahead switching plan. The presented approach can also be helpful in selecting the most practical switching action when the optimization engine can provide multiple optimal switching scenarios. The proposed tool is tested on a modified IEEE 118-Bus Test System to demonstrate its applicability and effectiveness.","PeriodicalId":6497,"journal":{"name":"2016 IEEE/PES Transmission and Distribution Conference and Exposition (T&D)","volume":"1 1","pages":"1-5"},"PeriodicalIF":0.0,"publicationDate":"2016-05-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"87543892","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 context, time synchronization is a very important issue, as many applications need to achieve high synchronization accuracy. The IEEE 1588-2008 standard [2] defines the second version of PTP, designed to achieve clock accuracy in the sub-microsecond range. In these scenarios Ethernet network redundancy is also important to assure system availability and fault robustness. PRP, defined in the IEC 62439-3 Ed. 3 [3], is designed to improve robustness to network failures with zero-time recovery.

Whenever safety for people or property is of primary concern, dry-type transformers are used. Traditionally dry transformers were only for MV distribution applications available, but recently dry-type power transformers were introduced for the 72.5 kV sub-transmission voltage class, with ratings up to 63 MVA. These transformers allow to easily construct substations in any building or underground location, without the need for costly fire protection. This allows to go with higher voltage directly to the main load centers, providing higher power and reducing distribution losses. Meanwhile several reference installations are in operation.","PeriodicalId":6497,"journal":{"name":"2016 IEEE/PES Transmission and Distribution Conference and Exposition (T&D)","volume":"58 1","pages":"1-5"},"PeriodicalIF":0.0,"publicationDate":"2016-05-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"86631361","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}

Now that increased pressures are being put on the grid by distributed generation and new loads, and the system is being held to closer tolerances through programs like conservation voltage reduction (CVR), it is becoming more important to understand the voltage drops at the LV service level. However, these voltage drops are rarely measured and reported on in the literature, particularly for US systems. This paper discusses three methods for measuring for LV secondary drop, using newly available measurements of customer voltage by advanced metering infrastructure (AMI) alongside other data. Based on AMI measurments and other data from three US utilities, it was found that while most secondary drops are within the ranges typically cited by utilities, there are a few spots with larger voltage drops that could be a problem given future CVR programs or the installation of additional load or PV.","PeriodicalId":6497,"journal":{"name":"2016 IEEE/PES Transmission and Distribution Conference and Exposition (T&D)","volume":"184 1","pages":"1-5"},"PeriodicalIF":0.0,"publicationDate":"2016-05-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"86874415","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 evaluating the reliability of power systems, several load curtailments are caused by voltage limit violations which can be alleviated using reactive power support. The existing methods of estimating the effects of voltage limit violations and reactive power limits do not provide the amount of reactive power support that is required to alleviate the violations. The presented work provides a quantitative measure of reactive power compensation for reliability improvement. This measure is based on constructing a probability distribution function for the required reactive power compensation. Reliability indices of Loss of Load Expectation and Expected Unserved Energy are used to estimate the lack of reactive power support. A non-linear, AC power flow based model is used to accurately represent system load curtailment remedial actions. A state space reduction technique is utilized to reduce the computation time. The proposed method is applied on the modified IEEE RTS and results show the improvement of power system reliability due to reactive power compensation.","PeriodicalId":6497,"journal":{"name":"2016 IEEE/PES Transmission and Distribution Conference and Exposition (T&D)","volume":"21 1","pages":"1-5"},"PeriodicalIF":0.0,"publicationDate":"2016-05-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"87169622","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 presents a new approach by using a lookup table (LUT) controlled resistance to suppress the GIC flowing through the neutral of transformers. The performance of the proposed method is compared with that of the currently adopted method, i. e, the fixed-capacitor method. In this work, the tested network consists of a single synchronous machine connected through a step-up delta/wye transformer, transmission lines, and another step-down transformer to an infinite bus. The MATLAB/SIMULINK software is utilized to carry out simulations. Simulation results show that the proposed method is able to stabilize the system under GIC events as well as mitigate the zero sequence current flowing during unsymmetrical faults. Moreover, the performance of the proposed method is better than that of the conventional method.","PeriodicalId":6497,"journal":{"name":"2016 IEEE/PES Transmission and Distribution Conference and Exposition (T&D)","volume":"34 1","pages":"1-5"},"PeriodicalIF":0.0,"publicationDate":"2016-05-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"80288885","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 recent solution to tackle environmental issues is the electrification of transportation. Effective integration of Plug-in Electric Vehicles (PEVs) into the grid is important in the process of achieving sustainable development. One of the key solutions regarding the need for charging stations is the installation of PEV Parking Lots (PLs). However, contrary to common parkings, PLs are constrained by various organizations such as municipalities, urban traffic regulators and electrical distribution systems. Therefore, this paper aims to allocate PLs in distribution systems with the objective of minimizing system costs, including power loss, network reliability and voltage deviation as possible objectives. A two-stage model has been designed for this purpose. PLs' behavior considering market interactions is optimized at the first stage to provide profit to the PL owner. At the second stage, the PL allocation problem is solved considering various network constraints. Conclusions are duly drawn with a realistic example.","PeriodicalId":6497,"journal":{"name":"2016 IEEE/PES Transmission and Distribution Conference and Exposition (T&D)","volume":"62 1","pages":"1-1"},"PeriodicalIF":0.0,"publicationDate":"2016-05-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"79900615","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}

Two approaches to identifying a reduced-order model are presented: a purely data-driven approach, and an approach that integrates online data-driven dynamic system identification with firstprinciple offline selective modal analysis. With prior knowledge of the frequency range interesting to power system operators, it is shown that the second approach recovers the key modes of the original system and produces a much reduced-order model of grid-level dynamics. Even with the presence of uncertainty about the actual modes of interest, an automatic tuning scheme is devised to adaptively adjust the frequency range to improve system identification.
