In this paper, for elimination of harmonics and increasing the quality of the voltage and output current of inverter, a three-level inverter is used, which connects micro-grid to a commercial electric power distribution system (utility one). An adaptive fuzzy PI controller was also used to control it, which then has a high pace of reply with a good performance in sudden changes of loads. The performance of micro grid in case of faults from utility grid was also analyzed. In this condition, the micro grid is disconnected from utility grid and act islanded. The connection and disconnection act of micro grid from the utility grid should happen rapidly. A simple method with a high speed is presented for this purpose. In the presented method, voltage domain and phase angel of both grids are compared. In case of outgoing of synchronism mode, micro grid is disconnected from the grid. The reconnection of micro grid happens when it is synchronized with the utility grid.

Due to the increasing need for energy and limitation in fossil fuels, wind speed turbines vary widely, despite their high costs in power plants, so it is essential to achieve maximum efficiency and maintain their sustainability. For this purpose, a variable speed winding turbine system is modeled with a dual power generator modeled in this uncertain system, such as variations in wind speed and uncertainty in modeling and parameter values. In order to improve the behavior of system outputs in the unstructured presence of uncertainties, a controller is designed using a sliding mode of the terminal to reduce the system shifting by combining the adaptive modeling theory to deal with the indeterminate parameters and control signal smoothing. In this method, the combination of interest is designed adaptively, and is independent of the boundary of the indefinite and independent determinants. Finally, simulation of the results has been done using MATLAB software. The simulation results show the proper performance of the proposed controller in an uncertain presence compared to other methods.","PeriodicalId":346749,"journal":{"name":"2017 Smart Grid Conference (SGC)","volume":"21 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121440570","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}

Moreover, there are several uncertainties and disturbances in the islanded microgrids that may lead to the instability. To solve this problem, this paper proposes the design of a multi-objective Linear Matrix Inequalities (LMIs) based regulator. It considers the LMI conditions in such a way that the design criterion holds. It also considers the disturbances, including solar radiation, wind speed, and load demand variations. With extracting microgrid state space model, it builds a framework to synthesize the controller. Next, it presents the mixed robust design criteria to set up the multi-objective function. The controller design process includes two steps: state feedback and observer designs. With considering weighing functions in the design process, it determines the optimal solution of the objective function. The obtained solution is the state feedback matrix, and it forms the controller by combining the state feedback matrix with a state observer. We have applied the designed controller to the islanded microgrid, and the effect of disturbances is evaluated together with parametric uncertainties. The proposed regulator is compared with the traditional PI method. The results show that the designed regulator has robust performance as well as robust stability.","PeriodicalId":346749,"journal":{"name":"2017 Smart Grid Conference (SGC)","volume":"20 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"117044383","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}

Due to PVs generation uncertainty and the necessity of energy economy management in the buildings, an optimal energy management method is needed that should be implemented based on the user critical load demand response with considering the storage capacity. This paper addresses a smart load management approach based on State of Charge (SOC) index to determine battery capacity in the condition of the PV generation uncertainty at 24 hours a day in the island state. It should be noticed that in the current load management method in the similar conditions the customers dealt with a power outage because the distribution network and customer devices will be protected from voltage fluctuation. The customer dissatisfaction and power generation uncertainty are the significant disadvantages of it. For this reason, to find a solution regard to smart demand response, it is suggested that the residential critical loads, categorized in three groups in which based on the smart selective program the target cluster loads supplied. According to the mentioned approach, 62% and 54% of winter and summer critical loads with considering the battery capacity in the island system are supplied, respectively. Furthermore, each electricity consumer average revenue in the condition of the PV generation uncertainty as the worst case (island state) are increased 1.93 $ and 2.91 $, respectively.","PeriodicalId":346749,"journal":{"name":"2017 Smart Grid Conference (SGC)","volume":"15 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121096759","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}

Consumption of fossil fuels has increased the density of greenhouse gases in atmosphere, which encounters the world with irreversible changes. In order to decrease the unwanted environmental effects of fossil fuel consumption a worldwide trend has begun towards the use of renewable energy resources. In this paper, Optimization of structure and final hybrid system cost are investigated in order to meet the electricity demand of Meymand village, located in Iran. To find the optimum hybrid system, HOMER software is employed. The hybrid system consists of wind turbine, solar panels and diesel generator as main generating resources in addition to battery as energy storage system. The considered lifetime is assumed to be 25 years, and not only technical issues but also environmental and economic issues are investigated. According to the simulation results, the net percent cost (NPC) of the proposed hybrid system is equal to $37180, and levelized cost of energy (COE) is equal to 0.2 $/kWh. The technical, environmental and economic evaluations show that satisfaction of demand of Meymand village is more advantageous by hybrid system rather than the traditional one.","PeriodicalId":346749,"journal":{"name":"2017 Smart Grid Conference (SGC)","volume":"144 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116264852","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}
