However, the traditional virtual signal injection MTPA control has the problems of static error or poor dynamic performance. In addition, the application of virtual signal injection method in permanent magnet assisted synchronous reluctance motor (PMa-SynRM) drives is rarely reported. Therefore, this paper proposes an improved MTPA control strategy with virtual constant signal injection for the PMa-SynRM drives. Based on the improved MTPA control law, the current reference value of the constant parameter is obtained in advance, and then the synthetic torque is generated by injecting virtual constant signal directly into the d-axis and q-axis currents. The derivative of torque with respect to current angle is extracted through simple linear operation, and then the q-axis current correction value is obtained when motor parameters change. This method avoids the use of filter. The simulation results show that the response time of the proposed method is shortened from 800ms of the virtual sinusoidal signal injection method to about 50ms when the load changes suddenly, and there is no steady-state error of the virtual square wave signal injection method.","PeriodicalId":447871,"journal":{"name":"2022 5th International Conference on Power and Energy Applications (ICPEA)","volume":"39 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-11-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128358926","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 solution time is decomposed into some series of time steps by finite difference, and the time step is determined as 10 minutes, which can satisfy the small calculation error when thermoelectric coupling. The steady-state numerical analysis method analyzes the steady-state temperature field to obtain the initial temperature field distribution of the buried cable. The entire transient temperature rise is solved time step by time step. Using an iterative approach, the load capacity can be solved for a given cyclic load waveform. The solution results are compared with the CYMCAP calculation results, and the numerical calculation results are significantly higher than the CYMCAP calculation results, which can effectively improve the current-carrying capacity and utilization of the cable.","PeriodicalId":447871,"journal":{"name":"2022 5th International Conference on Power and Energy Applications (ICPEA)","volume":"21 4","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-11-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"120860217","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}

Nowadays, much of the new power capacity installed is due to wind farms, onshore and offshore. The rapidly falling costs per kWh of wind power have made it more competitive with conventional power supply. However, the further development of onshore wind farms is restricted in many countries due to resource and environmental reasons. Therefore, offshore wind farms, which could overcome these limitations, have attracted more interest from the industry. Additionally, the offshore wind farms, mainly in floating offshore wind turbines (FOWT), owns high power efficiency due to being located in areas of constant and fast wind speeds. This study firstly reviews the major FOWT prototypes, Semi, Spar, and TLP, structures originally from the offshore oil industry. The review mainly focuses on the status of existing FOWT projects in Europe, Asia, and the United States. Lastly, the research identifies the technical challenges of FOWT that must be addressed to reduce the overall cost.","PeriodicalId":447871,"journal":{"name":"2022 5th International Conference on Power and Energy Applications (ICPEA)","volume":"121 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-11-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123043210","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 the upper layer control scheme, a Vehicle to Grid (V2G) control based on a time-sharing tariff strategy is proposed considering the economical benefits of both grid operators and EV users at the same time.
