Real time monitoring and optimisation are necessary to increase the flexibility, through solutions such as storage, demand response or flexible generation among others, to integrate higher shares of variable renewable energy and to serve the whole of the EU territory.Exploiting synergies between electricity, heating and cooling networks, gas networks, transport infrastructure and digital infrastructure will be crucial for enabling the smart, integrated, flexible, green and sustainable operation of the relevant infrastructures. Besides hydrogen and batteries other storage technologies are necessary to create a set of flexibility options. Similarly, integration of local, small, or micro grids raises a challenge at the level of the European energy network.Using highly efficient power electronics in power generation, power transmission/distribution and end-user application, together with advanced control solutions paves the way for the transition from the conventional and fossil-based energy system to a renewables based one.Important points of consideration for this transition are flexible generation, grid flexibility (network infrastructures), system stability and flexible operations, energy storage integration, demand side flexibility, advanced planning for flexible systems, innovative market design, business models and regulatory framework, secure digitalised energy system, integrated platforms for management and control of energy assets, effective and efficient solutions for transporting off-shore energy, direct Current grid solutions.Through system and technology development, European R&I strongly supports increasing the efficiency and effectiveness of the European energy system and help integrating it with its neighbours, accelerating the transition towards renewable energy, which is the key component for the EU to reach its 2050 decarbonisation objective.","PeriodicalId":236701,"journal":{"name":"2021 23rd European Conference on Power Electronics and Applications (EPE'21 ECCE Europe)","volume":"23 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-09-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121982397","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 proposed circuit has an n-series FCLA with only N-ch MOSFETs and an unfolder. The flying capacitor (FC) voltages are balanced by selecting the operation state of each MOSFET with phase-shifted carriers. FCLA outputs a continuous voltage that does not contain the harmonics that cause current harmonics. Due to this, the radiation noise from the transmission coils is reduced. The operation of the WPT system with the proposed 16-series FCLA is demonstrated in a simulation. The proposed FCLA output the sinusoidal voltage to the resonance circuit. In addition, the harmonics of the primary coil current are analyzed. From this result, the FCLA significantly reduces the current harmonics than the conventional two-level inverter. Then, The FC voltage balance is verified using the prototype with a 2-series FCLA. From the experimental results with a small-scale prototype, the proposed circuit outputs full-wave rectified sinusoidal output voltage with balanced FC. Furthermore, the harmonics of the unfolder output voltage are analyzed. From the analyzed result, the third-order harmonics are reduced by 19.8dB due to FCLA with MOSFET in the active-state in comparison with the theoretical value of harmonics of square wave voltage.","PeriodicalId":236701,"journal":{"name":"2021 23rd European Conference on Power Electronics and Applications (EPE'21 ECCE Europe)","volume":"9 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-09-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127927444","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}

Advanced metering infrastructure (AMI), allows monitoring and communication in the distribution grid, which could enable real-time optimal reactive power compensation by DG units. In this study, a real-time simulation using GridLAB-d and PSIM is used to explore this in a British Columbia, Canada grid. State estimation followed by reactive power optimisation is applied in real-time to both under-voltage and over-voltage grids. This process is shown to improve grid performance at very low cost, by either reducing power loss in the lines, mitigating reverse power flow or improving other objective(s) determined by the utility.","PeriodicalId":236701,"journal":{"name":"2021 23rd European Conference on Power Electronics and Applications (EPE'21 ECCE Europe)","volume":"252 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-09-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115849649","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}

Multi-terminal HVDC interconnectors provide the capability to integrate large-scale offshore wind energy into the main grid and secure at the same time the required interconnection capacity between various countries. Thus, multi-terminal HVDC networks for integration of offshore wind energy are currently pursued by the industry. This paper aims to offer guidance on finding the most suitable strategy for a shared dissipation of the excess energy in case of faults on the onshore ac side of the HVDC converters. For this different energy dissipation strategies are presented and discussed. Simulation results using PSCAD EMTDC are used to highlight the advantages and disadvantages of the different strategies.","PeriodicalId":236701,"journal":{"name":"2021 23rd European Conference on Power Electronics and Applications (EPE'21 ECCE Europe)","volume":"10 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-09-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131424768","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}
