This is forcing the distribution companies to take the proper actions in the planning of distribution system. The allocation of Renewable Energy Source (RES) and Distribution Static Compensator (DSTATCOM) are considered in the distribution system planning to reduce the losses and maintain the voltage of the system within the required limit with the growing load demand. Due to the environmental concerns, the RES is becoming the must to consider as a part of the power system whereas the use of DSTATCOM is for the reactive power compensation to improve the power quality and the voltage profile. For the simultaneous allocation of RES and DSTATCOM in balanced Radial Distribution System (RDS), Loss Sensitivity Factor (LSF) used to get the candidate buses and Particle Swarm optimization (PSO) algorithm is used for optimal sizes. For the calculation of load flow of the system an efficient Backward-Forward Sweep Load Flow Algorithm is used. The objective of the proposed methodology is to minimize the total cost which is the sum of total investment cost of RES and DSTATCOM, power purchase cost and pollution emission cost, keeping the voltage of each bus of the system within the limit. From the result obtained for the 38-bus balanced radial distribution system (RDS), it is clearly observed that the total active and reactive power losses are reduced and voltages of the system is improved with the optimal allocation of RES and DSTATCOM at minimum cost.","PeriodicalId":162808,"journal":{"name":"2022 22nd National Power Systems Conference (NPSC)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-12-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130889970","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}

Passivity of the admittance based on rectangular D-Q variables is a promising grid-connectivity criterion for devices connected to the network. This is facilitated by the inherent passivity of the D-Q based impedance of the electrical network. However, this criterion has been found to be too restrictive for the connected devices that have voltage magnitude and frequency-dependent power injection characteristics. Therefore in this paper, alternative formulations involving polar variables and active and reactive power are examined. The results presented in this paper indicate that (a) the wide-band polar formulation of the network is not passivity compliant, and (b) the polar formulation is suitable for developing passivity-based stability criteria for low frequency models, while the rectangular formulation can be retained for the high frequency models.","PeriodicalId":162808,"journal":{"name":"2022 22nd National Power Systems Conference (NPSC)","volume":"40 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-12-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132600039","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}

Thus, manipulating this system by foreign interventions like false data injection (FDI) must be handled with utmost priority. Power system monitoring using micro phasor measurement units (μ PMUs) gives more insight into the transient performance of the system. Using the optimal placement of PMUs, minimum numbers of μ PMUs will ensure the complete observability of the power system. This comprehensive view of the system can be used to detect any event that occurs in the system. The measurements of μ PMUs connected to the end points of each radial line can be used to detect the event location. But, any FDI-type attack on these devices can degrade the result of the event detection algorithm. In this paper, we work on IEEE 33 bus system to find the effect of falsified μ PMU data on the event detection algorithm. This work presents attack detection using a tolerance limits violation in the presence of an attack. Further, attack effect mitigation on the μ PMU readings is inspected to find its detrimental effect on the detection algorithm. Finally, the manipulated μ PMUs are detected, and their readings are avoided to get the proper event location.","PeriodicalId":162808,"journal":{"name":"2022 22nd National Power Systems Conference (NPSC)","volume":"22 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-12-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133115380","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 smart transformer delivers power from medium voltage (MV) utility grid to low voltage (LV) ac load. The triple-active bridge (TAB) converter plays a pivotal role in supplying power from LVdc bus down to various low-level dc voltages required by the data centres. This ST enabled TAB converter offers several features such as reduced conversion stages, high frequency power conversion, connection of alternate power sources, higher efficiency, power density and reliability.

One such dynamic phenomenon is low-frequency oscillation. Oscillation monitoring using PMU data has emerged as a significant application of wide-area stability assessment in power systems. The paper presents an analysis of oscillation events experienced in the North Eastern Region grid. The paper discusses three recent oscillation events of the system. Using archived PMU data of the event, this paper shows the computation of modal analysis using the matrix-pencil method. It highlights the reason behind the vulnerability of the system to oscillations. The analyzed oscillation events in this system indicate that the ac system strength of the system is weak due to the low effective short circuit ratio and low inertia constant. This is because the system is connected to a high dc link rating and has a low short circuit capacity.","PeriodicalId":162808,"journal":{"name":"2022 22nd National Power Systems Conference (NPSC)","volume":"18 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-12-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123206241","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}
