The smart grid architecture featuring electricity markets and distributed generation, with increasing penetration of Renewable Energy Sources, requires more accurate and faster forecasting algorithms. Meteorological parameters affect power generation in the case of conventional as well as Renewable Energy Sources. In this work, we propose the use of Kalman filters to correct the temperature forecast used to determine the expected output of a conventional gas turbine of a power plant participating in the wholesale electricity market in Greece. Time varying, time invariant and steady state Kalman filters are derived. The efficiency of the algorithms is tested through simulations. It is shown that the accuracy of the temperature forecast is significantly improved. The effect of the filtered temperature forecast on the expected of power output of a gas turbine is discussed.","PeriodicalId":317349,"journal":{"name":"2019 IEEE 60th International Scientific Conference on Power and Electrical Engineering of Riga Technical University (RTUCON)","volume":"27 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126444599","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 basic case study involving a traditional three-level h-bridge and a first order L filter was considered in order to magnify the effect of time horizon prediction and voltage over the regulated grid current waveform. An analysis related to the cost function composition over a horizon time prediction is then presented for different settings of the operational point. This paper presents only a part of obtained simulation results by means a model built a PSIM/Powersim. Even so, results show that one step forward could be classified as the most suitable form. And the number of involved applications could be even more since the fact that discussed results also indicate an unnecessity of higher processing time over several horizon time predictions for achieving the best results. Such conclusions would allow a smoother digital implementation of indirect MPC control method and result on a more efficient MPC controller in terms of energy effort in industrial applications.","PeriodicalId":317349,"journal":{"name":"2019 IEEE 60th International Scientific Conference on Power and Electrical Engineering of Riga Technical University (RTUCON)","volume":"6 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114137310","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 CDFs can be built from experimental data or can be approximated in accordance to assumed distribution function.
