In this paper, an improved Dual Grid Voltage Modulated Direct Power Control (D-GVM-DPC) strategies for unbalanced grid voltage condition is proposed and compared with regular voltage oriented dual PI control techniques. The idea of this improvement is to separately control the positive and negative sequence power components based on the original GVM-DPC controller. The simulation results shows that the proposed strategy is superior to the dual current control schemes been used with voltage oriented control strategy.","PeriodicalId":257974,"journal":{"name":"2019 IEEE Innovative Smart Grid Technologies - Asia (ISGT Asia)","volume":"48 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114675490","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}

With the further deepening of the sectionalizing, increasing boundary substations are going to have an unignorably impact on the quality of power supply in the urban grid. A strategy to limit the power flow during ring-closing operation without power cut based on load-transfer is proposed in this paper which starts with the theoretical analysis of the power system. In addition, through the simulation calculation of PSASP (the power system integrated program), a corresponding risk assessment tool has been set up to simulate and evaluate the risk of this ring-closing strategy towards boundary substation, which further reduce the risk during ring-closing operation. Furthermore, this strategy has been verified in the power grid plan of some city through the risk assessment tool.","PeriodicalId":257974,"journal":{"name":"2019 IEEE Innovative Smart Grid Technologies - Asia (ISGT Asia)","volume":"27 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116854610","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}

Firstly, the model of user side in smart grid including seven parts is constructed, which is more comprehensive and specific than previous research. Secondly, a multi-time scale optimal scheduling control strategy based on model predictive control is proposed. With the objective of minimizing the total cost in one day, a day-ahead economic optimization model has established. Then the model is solved by mixed integer non-linear programming. With the objective of minimizing the error between the daily scheduling and the actual output of the day, the intra-day rolling optimal scheduling model is established. Then the tracking of the daily schedule is realized by solving the model with rolling time-domain optimization strategy, which is based on model predictive control. Finally, the strategy is applied to a user side in smart grid in Beijing. The simulation results verify the feasibility and effectiveness of the optimization strategy. At the same time, the influence of different parameters (prediction time domain and unit climbing rate) on energy scheduling results is analyzed.","PeriodicalId":257974,"journal":{"name":"2019 IEEE Innovative Smart Grid Technologies - Asia (ISGT Asia)","volume":"6 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127287842","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}

To ensure the healthy operation of electrical equipment, periodic assessment of equipment status is required. Traditional neural network method has high evaluation accuracy and parallel processing capability. However the algorithm takes a long time to train and is difficult to converge. Latent Feature Model is an important evaluation method of e-commerce. It has the advantages of fast online calculation and high evaluation accuracy. The shortcoming of the model is that personal preferences have an impact on the assessment results. In this paper, smart meter is selected as the experimental object, and the Latent Feature Model is used to evaluate the health status of smart meter. In order to remove the influence of personal preference, this article adopts the k-means algorithm to cluster the influence factors which eliminate the assessment bias caused by personal preferences. Through the experiment of 1573 smart meters, the elapsed time of the Latent Feature Model is reduced by 29.34% compared with the traditional artificial neural network method, and the evaluation accuracy is only lowered by only 1.94%.","PeriodicalId":257974,"journal":{"name":"2019 IEEE Innovative Smart Grid Technologies - Asia (ISGT Asia)","volume":"51 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127509054","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}

Traditionally, thermal units are designated as the primary resources to provide ramping capacities. In this paper, we aim to exploit ramping capacities from many other flexible resources including the energy storage device and the demand response resource. A real-time economic dispatch framework is established, which clears the energy and flexible ramping products (FRP) jointly for each flexible resource. The proposed model can not only maintain a power balance at the current time but also accommodate any potential uncertainties in the future time. Line congestion issue is also taken into account in the proposed model. Mathematically, the problem is formulated as a two-stage robust optimization problem that is solved using an affine decision rule. An illustrative example demonstrates the effectiveness of our proposed model.","PeriodicalId":257974,"journal":{"name":"2019 IEEE Innovative Smart Grid Technologies - Asia (ISGT Asia)","volume":"251 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127539558","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}

To depict the correlation of the departure time, arrival time and daily mileage of EV, the Copula function is employed to generate relevant vehicle driving data for various types EVs. And the network constraint is introduced in this model, so that the charging and discharging scheduling plan of electric vehicle (EV) in each period can be reasonably distributed to the network nodes, and the system security is guaranteed. To deal with the complexity and non-linearity of the stochastic characteristics model with EVs, this issue is transformed into a mixed integer linear programming model and then solved by using CPLEX.
