However, the influence of the grid impedance ratio is always neglected due to the assumption that grid reactance is much large than grid resistance. In this paper, it is found that the grid impedance has a different impact on the stability with the reduction of grid impedance ratio. A large grid resistant can improve the stability of the grid-tied VSC due to that the grid resistance can increase the magnitude margin of the grid-tied VSC open-loop SISO transfer functions. Simulations are carried on Matlab/Simulink to verify the effectiveness of the proposed analysis.","PeriodicalId":146759,"journal":{"name":"2021 IEEE Green Technologies Conference (GreenTech)","volume":"56 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115404574","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 city which is located in the northwest of Saudi Arabia is planning to construct a power system that will shift the dependence on fossil fuels and achieve 100% renewable energy to energize the city and also provide clean energy for the country. The location is considered as one of the wealthiest natural resources in the region of solar energy and wind energy. NEOM's objective is to be a self-sustainable city and a center of renewable carbon-free energy. The paper consists of modeling solar panels and wind turbines technologies including nuclear power plant and simulations of the interconnected systems to achieve sustainable, reliable and resilient system. The modeling of the energy systems is performed by Vensim software considering different scenarios and power outages to provide an insight into the entire system's behavior and to ensure optimum sustainability. Moreover, the system will emphasize several variables that influence the structure of the system such as population, climate, and demand growth in residential, commercial, and industrial sectors.","PeriodicalId":146759,"journal":{"name":"2021 IEEE Green Technologies Conference (GreenTech)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123265588","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}

Aggregating smart EV charge controllers with other smart home devices through a home energy management system can lead to more optimal outcomes that benefit homeowners, utilities, and grid operators. Control strategies should consider occupant convenience by accounting for the need for fully charged EVs near the EV departure time. In this paper, we develop an EV charging framework that accounts for occupant convenience using OCHRE, a residential energy model, and foresee, a home energy management system. We simulate a community with high EV penetration and show that integrated, smart EV charging reduces peak demand and smooths night-time energy consumption. Simulation results show that the proposed control strategy nearly eliminates peak period EV charging and reduces the daily peak demand from EVs by 23%.","PeriodicalId":146759,"journal":{"name":"2021 IEEE Green Technologies Conference (GreenTech)","volume":"7 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123563056","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 addition to issues such as security, scalability, speed, etc., energy efficiency and sustainability should also be considered. In this paper, the proposed “green efficiency” characteristic is added to the quality model for the field of cryptocurrency. This characteristic consists of four units that have independent tasks, the overall process of which seeks to design an optimal quality model in terms of energy consumption in cryptocurrency. The central unit of this proposal is the G-ECC, which controls other units. The unit makes the final decision to reduce energy consumption and trade-offs between features by reviewing and evaluating reports received from other units.

This method of closed-loop optimal output regulation is achieved by utilizing measured data to approximate system dynamics, thus obviating the need for prior knowledge of system/plant dynamics. The underlying RL algorithm is then utilized to obtain the optimal feedback controller. The derived controller is obtained in a manner akin to that of a Linear Quadratic Regulator (LQR) and involves the iterative solution of an algebraic Riccati equation (ARE). This closed-loop control methodology is implemented on both buck and boost converters and its robustness to load and line variation is tested. A Type-III compensator was also developed in order to compare its performance with that of the proposed controller.

Due to the inherent characteristics, blockchain has been a preferred technology for realizing P2P energy trading.

In this paper, we introduce a P2P energy trading platform that leverages the popular blockchain technology and addresses these concerns. In particular, a multilayered semi-permissioned blockchain based platform along with a Quality of Transaction (QoT) module is proposed as a trading platform that can be used for transaction of energy. A two stage blockchain architecture, backed by QoT, ensures proper verification and validation of the participants and transactions. We present two use cases that demonstrate two different attack scenarios to highlight the resiliency of the proposed framework. Finally, a qualitative analysis shows the effectiveness of the system with respect to security, privacy and scalability.","PeriodicalId":146759,"journal":{"name":"2021 IEEE Green Technologies Conference (GreenTech)","volume":"4 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128837066","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}
