The model is assessed under varying water flows, device settings and diverse operational conditions that are unique to tidal applications.

Provision of such a service in both private and public sectors carries the burden of accumulating high electricity costs and the cost of energy consumption is surely to increase by a significant margin in the coming years. Green energy technologies require little maintenance when installed and this can be for an extensive period. These are quite robust since there is no equipment part wearing off, no fuel cost, and it is easy to increase the plant size to meet growing energy demand when needed. It provides a sustainable and reliable renewable energy investment that will result in savings returns for the user. The solution is premised on the integration of solar photovoltaic based renewable energy source installation with the main electrical supply grid of the building, thereby establishing a hybrid system that will provide secure and cheaper energy supply. The hybrid system will consist of an energy storage component and a 240V solar module PV plant installation to supply 40 kW AC power to augment the existing utility power supply and the standby diesel-powered generator. The AC inverter output power from the plant is fed to the critical load of the hospital during the day and it maintains a constant supply of hybrid renewable energy supply of PV with grid or PV with battery, when the embedded generator is no longer sufficient. This will ensure that there is security in power supply to the critical load, particularly between 6 AM and 5 PM when the system is active.","PeriodicalId":156687,"journal":{"name":"2020 6th IEEE International Energy Conference (ENERGYCon)","volume":"5 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-09-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"117074281","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}

This paper presents a cloud-based platform that analyzes power distribution grids data and deploys a service restoration application for the re-energization of loads after electrical faults. The implementation of this study is powered by FIWARE, which is based on open-source and customizable building blocks of future internet applications and services.

In turn, this reduced flexibility calls for additional balancing services. In parallel to this, the process of transport sector electrification is in place and the large fleets of electric vehicles (EVs) could prove to be one of the solutions for increased power system flexibility needs. If managed adequately, EVs could be able to provide the missing balancing services. In this paper, a model of EV day-ahead market and frequency containment reserve bidding is defined in order to asses the potential challenges that could arise during such service provision. Special attention is given to the EV battery state of energy, since the batteries are energy-limited resources and specific issues may arise both at individual EV and fleet level.","PeriodicalId":156687,"journal":{"name":"2020 6th IEEE International Energy Conference (ENERGYCon)","volume":"52 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-09-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124904300","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}

Islanded DC Micro-grid is implemented using multiple energy storage elements in parallel to ensure redundancy, reliability, and modularity. The conventional Half Bridge converter is compared with the interleaved topology (which is obtained by increasing the phase legs of half bridge) in terms of their frequency response analysis and SoC discharge when employed as interfacing converter between BESS and DC bus. The small signal or frequency response analysis is performed in Plecs using AC sweep, impulse response and multitoned analysis. It is established in this study from the open loop bode diagrams of the converters that the corner frequency of the interleaved is almost two times the half-bridge. This difference affected their SoC discharge when employed in a Micro-grid with the interleaved discharging at a rate almost twice that of half bridge. The interleaved also provides reduced current stress on the switch making it best suited for high power applications. The DC bus is 48V dc with a load power of 400W.","PeriodicalId":156687,"journal":{"name":"2020 6th IEEE International Energy Conference (ENERGYCon)","volume":"38 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-09-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129818098","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 this paper, an open source emulation model (made available on GitHub) has been developed for a Danish university teaching building to be applied in the MPC toolchain BOBTEST within the IBPSA project 1. The model is calibrated and realistic occupancy is introduced based on data measured by meters installed in the building. Simulation and sensitivity analysis performed on controllers and electricity-consuming devices helped to improve the emulator implementation and make it BOBTEST-ready.
