In this work, two separate classifiers based on long short-term memory networks are proposed to predict the stability status of a power system after being subjected to a credible fault. These classifiers use the immediate post-fault measurements of bus voltage magnitudes and rate of change of frequencies obtained from phasor measurement units during the first few cycles of the post-fault period. The proposed method does not assume that every bus is equipped with a PMU. It is found out that, even with only 30% of buses equipped with PMUs, the proposed classifiers are able to predict the stability status with an accuracy above 97%. Robustness of the classifiers is also investigated under noisy conditions and against the scenario of missing PMU measurements. A comparison between the two proposed classifiers is conducted by means of a t-test.","PeriodicalId":116136,"journal":{"name":"2019 7th International Istanbul Smart Grids and Cities Congress and Fair (ICSG)","volume":"173 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-04-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124233092","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, real-time monitoring and control of the smart grid (SG) for continuous and quality-aware power supply in smart cities (SCs) is challenging and requires an advanced quality of service (QoS)-aware communication framework. In this context, this research aims to present a novel data-gathering scheme by using the Internet of software-defined mobile sinks (SDMSs) and wireless sensor networks (WSNs) in the smart grid.

The OPF solution is generally sought by optimizing a selected objective, such as the generation cost, subject to security or reliability constraints of the power system. Nowadays, the aim of achieving a desired optimality is not an easy task because of many uncertainties due to various factors or components, notably the generation by means of wind turbines. In this paper, our focus is to present a multi-objective optimal power flow study to be performed for a power system that is considerably dependent on power generation through wind farms. A new risk-based method, information gap decision theory (IGDT), is used to tackle the problem of uncertainties in power generation introduced by the wind turbines. The objectives in the formulated optimization problem are the minimization of the fuel cost, the minimization of the voltage deviations from nominal values and optimizing the reactive power generation. The weighted sum approach is used to solve this problem using a single equivalent objective function.","PeriodicalId":116136,"journal":{"name":"2019 7th International Istanbul Smart Grids and Cities Congress and Fair (ICSG)","volume":"43 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-04-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126139994","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}

ESSs rule has become clear with the existence of renewable energy sources in the MG due to the intermittency nature of these resources. The MG faces different challenges during isolated mode of operation, such as load voltage fluctuation on the demand response, MG steadiness while supplementing of distributed generation (DG), and power flow instability. This paper proposes a robust control technique for superconducting magnetic energy storage (SMES) in isolated mode of operation of MG with the insertion of solar power generation (SPG) and the unexpected loading event as well. A fuzzy logic controller is used to control the power flow between the SMES and MG throughout regulating the bi-directional dc-dc converter duty cycle. Obtained results show the effectiveness of the proposed control scheme for mitigating the MG frequency, voltage and load current during SPG insertion and a sudden loading event.","PeriodicalId":116136,"journal":{"name":"2019 7th International Istanbul Smart Grids and Cities Congress and Fair (ICSG)","volume":"18 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-04-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123513195","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}
