In the case of islanded microgrids, the lack of cost effective, long duration storage options requires the integration of conventional fossil fuel based generation with these renewable resources for operation when sufficient irradiance is not available. This creates operational challenges as was the case for a midstream gas compressing, medium voltage, islanded microgrid recently installed and commissioned in the southwestern United States. Energization of 10MVA of PV plant and battery energy storage system (BESS) step up transformers created the risk of nuisance tripping of synchronous generator protection systems. As a result, this paper proposes to operate the BESS inverter in grid forming mode to utilize a soft-starting and synchronization procedure to avoid this scenario. An investigation is carried out to demonstrate modeling of the BESS and test the proposed solution during energization of the transformers and subsequent synchronization to a synchronous generator utilizing RTDS and controller-hardware-in-the loop testing of generating set controller hardware. The results of the investigation illustrate that strategic placement of the BESS and use of grid forming controls enable the energization of the PV plants while eliminating inrush currents and voltage sags characteristic of using synchronous generators. Furthermore, the proposed solution is demonstrated to be robust to the selection of inverter control parameters and transformer saturation characteristics.","PeriodicalId":350508,"journal":{"name":"2021 IEEE/IAS 57th Industrial and Commercial Power Systems Technical Conference (I&CPS)","volume":"13 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-04-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134006404","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 the last decade, wind and solar electricity generation have increased from 55 million MWh to 275 million MWh and from 2 million MWh to 96 Million MWh, respectively, in the US. Recently, FERC Order 2222 allows distributed energy resources, including distributed renewable generation and energy storage, to participate in the electricity wholesale market through aggregations. Limited rotating inertia of renewable generation resources results in reduced system inertia, which will increase the rate of change of frequency (ROCOF) due to sudden mismatches of generation and demand. During the high visibility national social event, the brightness of LED TV display put simultaneous demand change in power systems. With the development of slim, tightly packaged, and yearly update features of Smart TV, the penetration of different LED displays climbed rapidly from 9% to 60% in the US during 2012–2019. In this paper, the impact of societal events on frequency stability caused by large viewership on LED TV s is discussed. Increasing RESs penetration and FERC order 2222 are considered in this study. The power demand data of a 55-inch LED TV is collected and analyzed to address the problem. This study discusses the frequency stability issue caused by LED TV s in a low inertia power system. It can help system operators to develop frequency control practices accordingly.","PeriodicalId":350508,"journal":{"name":"2021 IEEE/IAS 57th Industrial and Commercial Power Systems Technical Conference (I&CPS)","volume":"59 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-04-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122185998","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 makes the problems of time delay, packet loss, noise and control signal distortion caused by chaotic time series. This paper presents a novel prediction compensation structure, which combines the signal hierarchical filtering method with gray prediction algorithm. First, utilize complete ensemble empirical decomposition with adaptive noise (CEEMDAN) method to decompose the PMU measurement signal into components with different frequency scales and use WOLF method to determine the chaotic characteristics of each frequency band component. Second, based on the analysis results of singular spectrum analysis (SSA), after removing the weak correlation information and noise corresponding to small singular values, reconstruct the known chaotic components. Third, add the components of each frequency scale predicted by gray Verhulst prediction method to get the final control input signal without time delay interference. Finally, the paper takes 5 communication scenarios to analyze that the proposed compensation scheme has a good compensation effect under different delays and packet loss.","PeriodicalId":350508,"journal":{"name":"2021 IEEE/IAS 57th Industrial and Commercial Power Systems Technical Conference (I&CPS)","volume":"32 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-04-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122277366","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 discrete wavelet transform is used to detect and classify either isolated or back-to-back capacitor switching transient signals. After that, the output from wavelet coefficients acts as the artificial intelligence input for discriminating the 6-difference cases of transient inrush current mitigation methods by using the combination of discrete wavelet transform and fuzzy inference system and discrete wavelet transform and probabilistic neural network. The proposed technique of discrete wavelet transform for detection and classification shows enhanced performance accuracy of 100 %.

In addition, they increase the efficiency of real power transfer. These benefits are amplified in an extra-high-voltage (EHV) system built from longer transmission lines, with expectations for higher reliability. Therefore, a reliable and practical design of EHV shunt capacitor banks is significantly needed. American Electric Power Company (AEP) developed a high-margin, EHV shunt capacitor bank design and protection scheme to reduce the number of failures and ensure proper protection of equipment. In addition, shunt capacitor bank switching may cause transients that can result in damage and misoperations of the capacitor and nearby equipment. This paper describes the design of the EHV (i.e., 345 kV) shunt capacitor bank equipment, protection scheme and transient response and mitigation - with the goal of improving the capacitor's availability and the system's reliability. The findings from this case study may be useful for other similar projects in the industry.","PeriodicalId":350508,"journal":{"name":"2021 IEEE/IAS 57th Industrial and Commercial Power Systems Technical Conference (I&CPS)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-04-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130468031","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}
