This increased penetration of renewable energy sources (RES) into the power system will affect system dynamics. This paper discusses the influence of integrating full converter-based renewable energy sources on different system stability indicators (SSIs) such as rate of change of frequency (ROCOF), frequency nadir, etc. Different test systems such as Kundur's two area model and IEEE-9 bus system are considered to evaluate the impact of different penetration levels of RES on power system stability indicators. The response of the system to common contingencies such as generator outage, load shedding, faults, etc. are studied using Dynamic Security Assessment Tools (DSA Tools) from Powertech Labs. It is observed that the post-disturbance dynamic behavior of a conventional synchronous generator-dominated system is significantly different from that of an inverter-dominated system and it is heavily dependent on penetration level, type of disturbance, type of RES, etc.","PeriodicalId":153735,"journal":{"name":"2021 9th IEEE International Conference on Power Systems (ICPS)","volume":"23 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-12-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116706371","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}

Unexpected weather conditions sometimes create widespread damage to the power system. The failure rate of equipment in power system along with redundancy and accuracy of forecasting decide the scope of damage. Eastern coast of Indian sub-continent experiences cyclones of varying intensity every year. These cyclones have severe impact on the infrastructure including the power infrastructure. The proactive operation strategy to counter each stage of uncertainty helps not only in managing the power system but also in early restoration. Amid the NCOVID-19 pandemic, Indian power system witnessed super cyclone named 'AMPHAN’ which originated in the Bay of Bengal. The cyclone, after landfall passed through densely populated regions affecting the load centers. Cyclone of matching severity was last witnessed by India in the year 1999. The landfall of cyclone started during afternoon hours of 20th May 2020. The proactive action strategy based on past experience resulted in minimization of loss to electrical system and power supply outage. This paper presents the proactive measures taken by POSOCO and power utilities across all key sectors, viz., generation, transmission, distribution, during different phases of cyclone trajectory and the impact of cyclone on Indian power system.","PeriodicalId":153735,"journal":{"name":"2021 9th IEEE International Conference on Power Systems (ICPS)","volume":"7 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-12-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121386104","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}

Considering the importance of power demand forecasting, different models, as well as many new techniques have been proposed in recent times. In this paper, two forecasting methods have been used and compared. The artificial intelligence method, Artificial Neutral Network (ANN) is compared with Vector Auto-regressive (VAR) which is a statistical method. The methods are used to predict the Hourly day ahead short-term load for the NER states of India with two cases i.e. Weekday and Weekend (Saturday & Sunday). The result for the Assam State of India for a period of three days i.e., 23rd–25th January' 2021 has been presented in this paper. The comparison utilizes the Mean Absolute Percentage Error (MAPE). The simulation results have shown lower average values of MAPE for the three days in the ANN model (7.01 % w.r.t. SEM and 7.42% w.r.t. SCADA) than in the VAR model (7.49 % w.r.t. SEM and 7.94% w.r.t. SCADA) indicating better accuracy by the use of the ANN method in predicting the electric power demand forecast of the North-Eastern Region of India. Further, the performance of the ANN model in load prediction is also compared with other machine learning methods such as Random Forest (RF) and Support Vector Machines (SVM).","PeriodicalId":153735,"journal":{"name":"2021 9th IEEE International Conference on Power Systems (ICPS)","volume":"40 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-12-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125311928","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}

Many nations have set ambitious targets to increase a significant share of EVs in near future. However, evidence from various countries shows that EV adoption is slow without proper policies and incentives. Despite the government's efforts to introduce regulations and programs for encouraging the use of EVs, the same problem is observed in India. An in-depth study on EV adoption policies of various countries can help in analyzing the pitfalls of existing strategies and initiatives to build an EV environment in India. In this context, the work aims to review EV adoption policies of various countries and Indian states. A comparison between Indian and international practices in terms of charging infrastructure standards, policies, and incentives to promote EV adoption is presented. Further, the work highlights the impact of EV adoption on socio-economic growth and possible challenges for Distribution Companies (DISCOMs).

In this paper, a MPC topology is proposed for battery and supercapacitor-based hybrid energy storage system which is suitable for low voltage high power application in a DC Microgrid. The converter utilizes a three-phase current fed Dual Active Bridge (DAB) structure which provides galvanic isolation between the battery bank and the load. A low voltage high power supercapacitor bank is integrated at the load side by means of two stage conversion to achieve high voltage gain. The wide range zero voltage switching (ZVS) of the three-phase current fed DAB and bidirectional operation between any two ports are the key features of the proposed MPC. In addition, the input current ripple of both the storage devices are greatly reduced due to the interleaved structure. The operation of the proposed MPC and closed loop control strategy are discussed. A 20kW system is designed and simulated in the MATLAB Simulink environment to verify the proposed converter topology.","PeriodicalId":153735,"journal":{"name":"2021 9th IEEE International Conference on Power Systems (ICPS)","volume":"2 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-12-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132543743","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}

A novel idea is discussed where the aerodynamic drag is used to harvest the energy from a car. This paper encloses virtual experiments and trials to use the vehicle's frontal area to channel the airflow at high speeds into a duct and generate power using a turbine generator system inside the duct. Numerous trials and simulations are done to optimize the experiment, and this paper gives a great insight into the possibility of harvesting energy utilizing the drag force experienced while driving a car at a considerable speed. The paper discusses the methods taken to design the duct inside the frontal area of the vehicle more efficient and robust in geometry, and also considers the shape of the frontal area so that it does not hamper the airflow reaching the duct, which in turn rotates the turbine forth the duct to generate power. All aspects of this paper are minutely taken care of, and the calculations are based on various assumptions mentioned in the paper itself.

The EV charging stations, which operate with the purpose of supplying energy to electric vehicles have the capability to be utilized for providing frequency control service to the distribution network along with regular operation of EV charging. The Battery Energy Storage System (BESS) has been deployed at the EV charging station to avoid the instability to the grid at the time of providing fast charging and the utilization of this BESS has created a new opportunity of providing frequency control service to the grid. Proper coordination is needed to be maintained between the fast charging of EV and frequency control service for frequency regulation. Also the integration of solar PV at distribution network can support the EV charging stations for improving the power quality of the distribution network. Optimally located distributed generation sources are capable of providing sufficient contribution to improve the power quality of a distribution network and its effectiveness has been shown at this research work by utilizing BESS and solar PV. The developed algorithm ensures the proper functioning of the two type of EV charging stations with the objectives of providing charge to EV and also providing frequency control service to the distribution network while maintaining the constraints of the battery so the SOC level stays within a required limit to ensure the smooth operation of both of these objectives.","PeriodicalId":153735,"journal":{"name":"2021 9th IEEE International Conference on Power Systems (ICPS)","volume":"72 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-12-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133746654","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}

Beyond the specified limits, however, these must be brought within the specified band by appropriate means. Operators achieve this by rescheduling generators or by calling up ancillary services. The amount of violation of flow/voltages must be first determined for this purpose. The proposed work obtains flow and voltage profiles as a function of the network parameters and injections for which a new approach is used. Its similarity with fractals is explained. Generators that have a dominant effect on a particular line flow or load-voltage are uniquely identified in the analysis. The corrective mechanism is then implemented for mitigating violations. Fractals are products of scalar multipliers for injected powers. The scalar multipliers are functions of network parameters and structure and need to be evaluated only once. The method is in sharp contrast with those employing sensitivities. The computation of cost of mitigation is direct and does not need an optimization with Lagrange multipliers. The method is expected to be useful to system operators in market-based power systems and for, designing at the planning stage, and calling up ancillaries during operation. Charges for congestion or voltage violation can be analytically obtained to the satisfaction of stakeholders.","PeriodicalId":153735,"journal":{"name":"2021 9th IEEE International Conference on Power Systems (ICPS)","volume":"20 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-12-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131811536","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}
