The method of using innovation vector for bad data detection is available by default in tracking state estimators. In this paper, we investigate the possibility of extending the usage of the innovation vector available with tracking state estimator to estimate the ratio correction factor (RCF) of instrument transformers (ITs) using synchrophasor measurements. For this purpose, tracking and normal state estimators are considered on a three-bus, two-line system. One voltage measurement and one current measurement was biased, once with a magnitude correction factor (MCF) of 1% and then with a phase angle correction factor (PACF) of 1 degree. Normalized innovation is used for detecting bias errors. It is shown that the tracking state estimator will not identify a systematic error in IT. If we treat moderate or small RCFs as bad data in tracking state estimators, we find that the innovation vector is no longer zero mean. However, it is not large enough to pass statistical thresholds of bad data detection. Also, due to smearing, pinpointing the location of bad data is difficult. Hence, it appears challenging to develop IT calibration methods along these lines.","PeriodicalId":162808,"journal":{"name":"2022 22nd National Power Systems Conference (NPSC)","volume":"688 ","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-12-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"120877891","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}

In general, as compared to conventional substations the digital substation needs lesser space for smaller trenches, lighter trays for faster installation & commissioning easier access for maintenance. Digital substation reduces operating expenses (OPEX) budget. Digital substation is the one of the important aspects of modern electric grid, which needs to be more resilience to meet growing energy needs like electrical vehicle charging stations, extreme weather condition impact on renewable energy generation, distributed energy resources and prosumers. Real time visibility of fluctuations in generation and load management is highly required in current power generation pattern due to distributed energy resource/generation. Real time awareness of grid to the operator reduces the outage impacts by eliminating the faulty area on time there by avoids cascading events and reduces the number of customers get affected by outages. Larsen and Toubro (L&T) understood the need of the latest state of art digital substation technology to enable the future world to meet modern energy requirements and upgraded the existing conventional 33/0.415 kV and 11/0.415 kV substations in chennai headquarters (HQ) campus with Intelligent Electronic Devices (IED) using digital substation principles. L&T upgraded two substations not only to improve the monitoring and control capability in more intelligent way, but also to observe and analyze the challenges faced while converting conventional substation to digital and enhance L&T expertise on digital substation technology and prepare for future market. In this paper, we present the overall architecture, the lessons learnt during the implementation of digital substation project.","PeriodicalId":162808,"journal":{"name":"2022 22nd National Power Systems Conference (NPSC)","volume":"25 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":"126658744","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}

Though EVs have long been regarded as a game-changer in India’s automotive industry, a proper charging infrastructure is critical for the proliferation of EVs alongside the integration of renewable energy sources into the grid to develop a low-carbon society. This combination of uncertainty revolving around EV charging operations and the presence of decentralised small-scale renewable energy sources add complexity to the energy management process and the establishment of fair pricing at the grid level. In this paper, an ecosystem blueprint for an EV charging station has been proposed, which includes a dynamic pricing model for charging Electric Vehicles in any office or college space which acts as a hybrid microgrid with renewable energy sources. This work has been validated for NIT Trichy as a case study and solar PV is taken as the main renewable resource. However, the proposed model can accommodate the future addition of any renewable source and can formulate the prices accordingly. The proposed pricing model aims to maximise user satisfaction by keeping the charging bills low, as well as maximise the utilisation of renewable energy to lower the dependency on the grid. The blueprint also includes a comprehensive business plan to discuss its feasibility. Furthermore, the blueprint also involves building a suitable interface for EV users through a mobile application to efficiently book slots and charge their EVs and an admin dashboard supervises all the operations and helps keep an eye on the operational constraints.on the operational constraints.","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":"121554606","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}

Being the most dynamic and unique one to control, invariably it must be optimized in an effective way. The increase in population will also require additional generation of energy which can’t be abated as it effects the growth of people in all ways. So currently, the need to use energy-efficient devices and techniques at the Demand Side is same as the need to generate electricity through the renewables. Home Energy Management Systems (HEMS) is used for optimizing and scheduling load in the demand side along with renewable integration. This paper briefly reviewed HEMS by discussing its architecture, components, appliance classification and its objectives to manage the load demand at the residential level due to integration of different devices along with their uncertainty’s considerations. Furthermore, this manuscript also provides detailed summary of several prediction and scheduling techniques used in the recent studies which can be used further. As it is a well-diversified and a fast-growing field in the real time applications, it still needs further development in coordination between its own devices and with the upper-level utilities to reach its full potential.","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":"130506590","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 mitigate this challenge, this paper proposes a multi-energy system-based community microgrid, which consists of various electrical and thermal generation units, thereby allowing localized generation-load matching. In particular, the selected community microgrid system consists distributed energy resources such as solar PV system, battery energy storage system, and a biomass gasifier for power production. On the other hand, high power-consuming loads such as cold storage, a flour mill, critical, and domestic loads within a village are also modeled and included, through actual surveying in a rural location in India. Further, using these demand and generation inputs, the optimal dispatch schedule for the proposed multi-energy system is obtained by solving a mixed integer non-linear programming problem. It is shown that the proposed multi-energy system can meet the demand of the village cost-effectively, subject to the operational constraints of all appliances and generators. Additionally, based on the economic analysis of the system, this paper also develops a self-sustainability plan for the microgrid operation for the socio-economic welfare of the community.","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":"130796007","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 metering infrastructure is essential and must be the nodal points of measurement to anticipate high peaks of power demand or potential cyber attacks in order to avoid power outages of the grid. The paper suggests a novel architecture for the smart grid for grid resilience, which incorporates cloud computing resources and EIoT to do the energy consumption prediction, meeting the demand responses and keeping the grid away from cyber-attack threats.
