In this study, a combination of Monte Carlo Simulation (MCS) and Multilabel Radial Basis Function (MLRBF) classifier is used for computing system reliability indices. Multilabel classification algorithms is different from single label approaches, in which each instance can be assigned into multiple classes. This study shows that MLRBF can be used to classify composite power system states (success or failure) without requiring optimal power flow (OPF) analysis, with exception of training phase. Therefore, this approach shows that the computational efficiency of the reliability evaluation analysis to evaluate reliability indices can be significantly increased. The proposed method is applied to the IEEE Reliability Test System (IEEE-RTS-79) for different load levels. The outcomes of case studies show that MLRBF algorithm provides good classification accuracy in reliability evaluation while reducing computation time substantially.","PeriodicalId":185930,"journal":{"name":"2018 20th National Power Systems Conference (NPSC)","volume":"18 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126970653","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 proposed stabilizer can damp the electromechanical modes as well as the oscillation modes introduced by Converter Control Based Generators (CCBGs). A new weight-function for complementary-sensitivity function of system is proposed to improve robustness of the stabilizer. The weight function is developed by utilizing information from different operating points of the power system so as to improve the robustness. Controllability and observability indices are used to evaluate the effective input-output signals and the placement of ESS stabilizer. Detailed dynamic model of ESS representing energy storage, converter, PWM and filter dynamics is considered in the design procedure of the stabilizer. The physical limitations of ESS are considered in the stabilizer design by incorporating a new sensitivity function in to the objective function of H-infinity control. The IEEE-39 bus system is modified to represent 50–70% RE penetration level. Small-signal studies and time-domain simulations of the modified system are performed to verify the effectiveness of the proposed ESS stabilizer. Cost benefit analysis and sizing of the stabilizer falls out of the scope of this paper.","PeriodicalId":185930,"journal":{"name":"2018 20th National Power Systems Conference (NPSC)","volume":"15 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126533860","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}

PV generation would reduce the generation share of synchronous generators and hence reduce generator inertia & PFR. This necessitates an additional response from interruptible loads, to make frequency stable following contingency like generation outage. In this regard, this paper proposes a novel interruptible load (IL) constrained PFR scheduling framework with the objective of operation cost minimization. Case studies are carried out on IEEE RTS 24 bus and the performance of the proposed approach is analyzed in terms of PFR, IL and operation cost with variation in PV penetration. Results obtained shows that IL response supports the system frequency at conditions like low demand and minimum inertia following largest generation outage. Proposed model could be potentially enhanced to incorporate response from other load types and technologies like energy storage and electric vehicles.","PeriodicalId":185930,"journal":{"name":"2018 20th National Power Systems Conference (NPSC)","volume":"47 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124494875","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}

Non-cooperative game theory is applied to frame the distributed load scheduling game, where the consumers are considered as the players and the energy consumption schedules of their appliances as strategies. Genetic Algorithm (GA) is used as the optimization tool for individual consumer load scheduling to minimize the electricity bill.

Convexification of OPF is desired in order to reduce the complexity of solving such problems. Existing convex formulations such as Semi-Definite Programming (SDP), conventional Second Order Conic Programming (SOCP), and so on and their variants result either in significant optimality gap (OG) or reduced OG, albeit with the presence of non-convexity or approximations which bridge the gap between convexity and non-convexity. Due to these challenges, the current practice in the electricity sector is still to use the DCOPF (approximation of ACOPF). Hence in this paper, an exact and novel SOCP formulation of actual ACOPF has been proposed which aims for getting an equivalent convex formulation similar to the actual nonlinear, non-convex ACOPF. This also ensures attaining zero OG for mesh as well as radial networks and hence, the possibility of easily integrating this formulation in OPFs with data uncertainty. The proposed methodology has been tested on a 3 bus, IEEE 14 bus and IEEE 118 bus test systems on GAMS platform. The results thus obtained, have been compared with those obtained from DCOPF, nonlinear, non-convex ACOPF, conventional SOCP formulation for radial networks (SOCP-I) and conventional SOCP formulation for mesh networks (SOCP-II). The results ensure zero OG of the proposed SOCP formulation.","PeriodicalId":185930,"journal":{"name":"2018 20th National Power Systems Conference (NPSC)","volume":"17 1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134322467","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}

It also helps in protecting and increase the longevity of the electrical equipment. The electrical consumption data is measured usually using the multifunction meter(MFM) installed in residential or commercial buildings. In the commercial buildings, these meters are installed in the panel room(centralised) and in all floors/departments(decentralised). The extraction of data is the first step for the process of data analytics. This paper discusses how the extraction of data is possible from these installed multi function meters. In order to demonstrate the data retrieval process, a hardware lab set up is implemented using RS 485 communication interfaced multifunction meter(MFM). In addition to the MFM, certain modules(both hardware and software) used for the data extraction are also explained in a step by step manner.

In this work, the superimposed components of current signals are taken as features for performing the detection and classification task. For fault section identification, the voltage and current superimposed components are used together. Performance of the proposed technique is assessed for numerous test cases by generating data on a 230 kV UPFC compensated two machine system through EMTDC/PSCAD.
