Therefore, it is one of the cleanest and most efficient technologies. In a FC, energy is not generated by combustion and generated by an electrochemical process. In this paper, modelling and simulation of a grid-connected Solid Oxide Fuel Cell (SOFC) unit is presented. The output voltage of the FC unit varies by load changes and its DC link voltage is stabilized by a DC-DC boost converter. A full-bridge three-phase inverter is also used to convert the output DC voltage to AC voltage. The linear model of power electronic converters are used to control the effects of load changes and reference power variations. Since the inverter is connected to the grid, the inverter control method is based on the Grid-following mode. The simulation results in MATLAB/ SIMULINK software validates the presented modelling and control strategy in the load and power reference change scenarios; so that the DC link voltage always remains constant and AC voltage of the inverter output also keeps its synchronism with the grid. The FC unit is able to inj ect generating power into the grid in addition to providing its local load.","PeriodicalId":395659,"journal":{"name":"2022 26th International Electrical Power Distribution Conference (EPDC)","volume":"128 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-05-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128463353","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}

GTO method is used to design microgrid parts due to its high effectiveness in determining the optimal solution in a short time. The objective function of this paper is to reduce the system's cost of energy (COE), minimize the net present cost of the proposed hybrid system (NPC), and calculate the probability of insufficient power supply operation using the factor of loss of power supply probability at the system parts (LPSP). In this paper, statistical analysis is used to determine the optimization methods' capability in finding the optimal solution. The results obtained by GTO are compared with other known optimizers, namely Ant Lion optimization (ALO) and Gray Wolf optimizer (GWO), in order to prove the effectiveness of GTO approach. The results of the simulation indicate that the best design of the system is achieved by GTO over the other algorithms.","PeriodicalId":395659,"journal":{"name":"2022 26th International Electrical Power Distribution Conference (EPDC)","volume":"11 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-05-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126636405","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 imbalances can cause the operation of relays and frequency instability, as a result. On the other hand, in a microgrid, increasing the penetration factor of wind and solar energy can cause lack of frequency control due to uncertainty of generating output power and also low inertia of these resources compared to other conventional sources. Furthermore, Adjusting the gain of droop and inertia control loops is very effective on frequency stability performance. However, due to the wind speed and solar radiation fluctuations as well as load changes, it seems impossible adjusting the mentioned control coefficients with conventional PI controllers expecting the best response in all conditions. Therefore, this paper, by modeling load changes and wind and solar generating power and the participation of battery energy storage and diesel generators in the microgrid, proposes a control method based on virtual inertia compensation and also a fuzzy-neural controller for faster performance and more robustness. In the end, the results of this control strategy will be compared with other conventional controllers.","PeriodicalId":395659,"journal":{"name":"2022 26th International Electrical Power Distribution Conference (EPDC)","volume":"32 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-05-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129129596","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}

An active distribution system consists of several Micro-Grids (MGs) each of which has kinds of Distributed Generations (DGs) and Demand Response (DR) resources. Hence MG optimal operation is bi-level optimization problem whose upper level seeks for micro-grid owner profit and the lower level corresponds to distribution companies (DC) profit. In such a system MGs can exchange power between each other as well as distribution company. Therefore, upper level problem determines DGs generation, curtailed load, power exchange with other MGs subject to load balance constraint. Also Distribution Company (DISCO) clears retail market. On the other hand, renewable energies uncertainty and variably makes the MGs operation more complicated. In this paper, renewable energy variability handled by shift able load management and their uncertainty has been managed by curtailable load. The developed model has been solved by Particle Swarm Optimization (PSO) for upper level and then with given population in each iteration, lower level problem has been solved completely by other PSO package. This process ends when upper level PSO converge. Numerical studies have been shown that renewable management by proposed model leads to more optimal solutions.","PeriodicalId":395659,"journal":{"name":"2022 26th International Electrical Power Distribution Conference (EPDC)","volume":"338 7","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-05-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"120907354","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}
