The task of the EMS is to efficiently balance power generation and consumption by controlling various energy sources, including photovoltaic systems, energy storage units, engine generator set and the utility grid. An EMS optimizes power flow between the microgrid components and keeps the micro-grid stable, by using different control strategies. In this microgrid, the PV system serves as the primary energy source, while the other sources of electrical energy act as backups. The energy management system prioritizes supplying load demand from either the PV system or the other sources, with load shedding during peak hours if the supplied energy is insufficient. The approaches based on StateMachine and StateFlow are discussed in this paper for enhancing the energy management system's performance.","PeriodicalId":153848,"journal":{"name":"Algerian Journal of Signals and Systems","volume":"56 4","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-12-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139131034","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 value of the temperature coefficients provided by the module manufacturer in the datasheet is obtained under specific conditions called the standard test conditions STC, but in reality, these conditions vary significantly if the modules are operated in real climatic conditions, this will lead us to recalculate these coefficients again to improve our model using a database collected over a period of one year obtained by our characterization bench of PV modules using a two diodes model. A comparison was made between the simulation and the experimental data of the selected modules using the new values of the calculated temperature and those given at STC conditions, the obtained results show that the use of these new calculated temperature coefficients leads to a reduction of the the Mean Relative error MRE on the annual power from 2 to 7% depending on the PV module's technology which shows the importance of knowing the real value of the temperature coefficients that will be used in the PV module and system modeling.","PeriodicalId":153848,"journal":{"name":"Algerian Journal of Signals and Systems","volume":"10 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-06-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115402564","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, this type of controller is less efficient due to a sign function that can lead to chattering phenomenon. To overcome this deficiency, the function is replaced by fuzzy logic control (FLC). This is what is proposed in this paper which deals with doubly fed induction generator (DFIG) based wind turbine conversion system (WECs) by sliding mode control and fuzzy sliding mode control (FSMC). The system control have been applied to the back to back converters that connect rotor windings to the grid, For the rotor side converter (RsC), we have presented sliding mode control, and fuzzy sliding mode control to monitor active and reactive powers independently, when the grid side converter (GsC) was set to keep a constant DC voltage with a desired power factor. The effectiveness of the proposed control systems is tested using Matlab/Simulink software under a wind speed fluctuation and parameters variation.

The dc voltage is maintained constant using proportional integral voltage controller. To get the reference signals for shunt and series APFs, synchronous current detection method (SCD) and instantaneous reactive power (PQ) strategies are adopted. These reference signals are derived from the control algorithm and injected in LS-SPWM (Level Shifted-Sin Pulse Width Modulation) controllers to generate the switching signals.
