The conventional unidirectional boost converter is controlled to interface a photovoltaic module with a battery array and the electromechanical actuator of the gate, this allowing the operation of the system in the absence of solar irradiation. The work develops modelling of the proposed system in order to deduce a single controller regulating input voltage which is able to operate in the whole set of operation conditions of the system. The resulting system can be used to develop current or voltage outer controllers. Simulation results regarding response to different disturbances confirms its correct operation.","PeriodicalId":230738,"journal":{"name":"2021 IEEE 5th Colombian Conference on Automatic Control (CCAC)","volume":"15 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-10-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127382312","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}

Through this formulation it is possible to calculate the harmonic power flow independently of the fundamental power flow, which is an advantage when working with tertiary control problems in microgrids. The algorithm with which the formulation was simulated is presented. The fundamental and the harmonic power flow are implemented in a modified CIGRE test case for microgrids. Finally, an evaluation of the harmonic distortion associated to the PV systems modeled is exposed, and performance evaluation is also presented by comparing the presented approach with the currents injection harmonic power flow method starting from an iterative power flow.","PeriodicalId":230738,"journal":{"name":"2021 IEEE 5th Colombian Conference on Automatic Control (CCAC)","volume":"8 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-10-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128505195","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 proposes an optimal management model of this type of microgrids under the minimum operation cost goal. The mathematical formulation is presented in detail, which involves constraints related to the operation of the system over a time horizon of a week.

The framework was implemented by modifying the Energia IDE, which is an Open-Source software similar to Arduino IDE, but oriented exclusively to some Texas Instruments microcontroller families. Energia IDE was modified to support a new board based on the F2837xD microcontrollers family, to achieve this, we performed some experiments and modifications in files from Energia IDE through tools like Load TI and UniFlash. In addition, we created new source (.c) and header (.h) files similar to those used by Code Composer Studio. Finally, we designed an API for the implementation of digital control strategies and resource management in C2000 microcontrollers.","PeriodicalId":230738,"journal":{"name":"2021 IEEE 5th Colombian Conference on Automatic Control (CCAC)","volume":"114 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-10-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124383653","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}

However, the pH is one of the most difficult variables to control, because it is a nonlinear system with multiple disturbances. This paper proposes successful control strategies for the alkalized juice system. In particular, a cascade control with feedforward and feedback configuration to control pH and a function of level versus pump speed to minimize disturbances associated with input juice flow rate. A preliminary process characterization is obtained with the Ziegler-Nichols method, which validates the long system dead time. In this way, the system is modified to change its dynamics. The proposed strategies are implemented in one of the main plant producers of ethanol in Colombia. The qualitative and quantitative results show the effectiveness of the control strategies in a comparative study of three cases.","PeriodicalId":230738,"journal":{"name":"2021 IEEE 5th Colombian Conference on Automatic Control (CCAC)","volume":"6 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-10-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125866417","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 proper management of these loads produces a reduction in energy demand. Colombia is an agricultural country, one of its favorite products is flowers. That product needs to be refrigerated for three months to maintain its quality or complete many flowers (a batch) to export and commercialize. In favor of this reason, it is crucial to have an exemplary refrigeration system or improve the current one. This article presents the comparison among some standard system identification algorithms. This development is vital to the flower greenhouses in the Boyacá region to improving efficiency in the post-harvest stage. Matlab software makes the data processing and executes some system identification algorithms in order to determine the most suitable tool for flower greenhouse cooling systems.

As a result, the N4SID algorithm presents the best performance with a fitting of 81.23%.","PeriodicalId":230738,"journal":{"name":"2021 IEEE 5th Colombian Conference on Automatic Control (CCAC)","volume":"28 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-10-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124730047","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}
