Solving this problem would provide key enablers for meeting the needs of very diverse social-ecological energy systems (SEES) across the world. As a way forward, we propose a unified modeling framework which is a formal description of a system in multi-disciplinary terms that allows research and results from different domains (engineering, economics, and environment) to interact and be incorporated into a cooperative solution. The framework is based on general laws of physics and economics defining interactions within an SEES. Interaction variables are technology- and policy-agnostic and are used to model mutual effects of different system participants (modules) expressed in terms of common: engineering variables (power, rate of change of power, energy, time); economic variables associated with the same physical variables (prices, time); and, environmental variables (pollutant mass). We describe how the proposed modeling can be used for deployment of cyber systems solutions at value. Simulation approach based on the same unified modeling is essential for educating ourselves regarding their potential technical impact on reliability and resiliency, economic and environmental impact on value created to different industry participants in different network architectures.","PeriodicalId":296428,"journal":{"name":"2017 North American Power Symposium (NAPS)","volume":"355 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122800511","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 general, the wind power generation is highly dependent on accurate and reliable wind speed prediction. Therefore, the wind speed forecasting is very important as well greatly influences on the scheduling of a power system and the dynamic control of the wind turbine and resource planning. The main objective of this paper is to forecast the wind speed for short-term from the previous wind speed data. In this paper, a Gaussian Mixture Regression (GMR) model is applied for forecasting the wind-speed for short-term (Two-hours ahead). Moreover, in this work the real-world wind data sets were used in order to model training and testing. The GMR model is simulated in Matlab software. The proposed GMR model is evaluated in terms of Root Mean Square Error (RMSE), Mean Absolute Percentage Error (MAPE) and Mean Absolute Error (MAE) in the task of short-term wind speed prediction. From the simulation results and numerical analysis, it can be stated that the prediction of the short-term wind speed is very accurate by using the GMR methods.","PeriodicalId":296428,"journal":{"name":"2017 North American Power Symposium (NAPS)","volume":"193 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123312800","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}

Hence, DG units should be controlled to form the frequency and voltage, pick up the full load, and respond to any load changes. Conventional P — f/Q — V droop controller enables a communication-less load sharing among DGs while maintaining close deviations of frequency and voltage. Utilizing the dq-frame power flow analysis, this paper presents an equivalent primary droop controller id — f/iq — V based on the direct and quadrature components of the feeder currents, which are already existent in each voltage controller for disturbance rejection. More emphasis is placed on the phenomenon of inaccurate reactive power sharing caused by mismatched feeder impedances. Analysis is presented in terms of the droop equation, and compensation methods are examined with focus on computation and communication requirements, and PCC voltage profile. For validation of the controller's response, a testbed model exhibiting the dynamics of a two-DG microgrid is developed and simulated in Matlab/Simulink.","PeriodicalId":296428,"journal":{"name":"2017 North American Power Symposium (NAPS)","volume":"36 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131805320","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}

Power converters featuring WBG devices have higher power density and are more efficient and reliable than those using existing silicon (Si) devices. This paper presents the design of a non-isolated dc-dc buck-boost converter and evaluates the impacts of three power devices on converter performance. To evaluate overall performance, three buck-boost converters are designed and tested: one with a Cascode GaN FET, one with a SiC JFET, and one with a Si IGBT. Additionally, a SiC Schottky diode is implemented in each converter to reduce switching energy loss of power devices and improve converter performance. The switching behavior and energy loss of three power devices are evaluated at various junction temperatures. Total power loss and efficiency of each converter are compared at different switching frequencies, output power levels, and operating temperatures. The results show that the Cascode GaN FET-based converter yields considerable improvements in switching performance, total power loss, and overall efficiency.","PeriodicalId":296428,"journal":{"name":"2017 North American Power Symposium (NAPS)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129898419","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}
