A method for predicting the remaining life of a transformer based on digital twin technology is proposed: establish digital twin of a transformer with digital twin technology, and using a multi-physics coupling method to calculate the change law of the digital twin’s winding hot spot temperature parameters under different working conditions and different operating hours, thereby establishing a remaining life prediction model based on the digital twin’s winding hot spot temperature data.

But the weighting factors of the cost function are difficult to tune appropriately and need extensive simulation and experimental tests. This paper proposes a model predictive control strategy based on hierarchical feedback. By establishing the feedback mechanism between alternating current and circulating current control, the number of inserted submodules (SMs) of upper and lower arms are quickly determined to realize the optimal control of multiple objectives, and the tuning process of the weighting factors is eliminated. The computation burden of the cost function is reduced by the preselection of the inserted SMs combination. MPC with the Hierarchical Feedback control can generate $2N+1$ output voltage level in the MMC while suppressing the circulating current. Finally, an MMC-HVDC system has been developed to verify the validity and effectiveness of the proposed method.","PeriodicalId":411512,"journal":{"name":"2021 3rd International Conference on Smart Power & Internet Energy Systems (SPIES)","volume":"75 2 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-09-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128059479","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}

A variable droop adjustment coefficient control method for doubly-fed wind turbines participating in the primary frequency regulation of the power grid based on the gray wolf optimization algorithm is proposed. It can adjust and optimize the droop control coefficients of the doubly-fed wind turbines for different wind speeds and improve the control accuracy.

The inverter consists of an impedance network with enhanced-boost ability, a single-phase inverter bridge, and an output LC filter, adopting the unipolar SPWM control strategy with instantaneous feedback of output voltage and energy storage capacitor voltage. The impedance network is cascaded by an energy storage inductor and n identical diode-inductor-capacitor-capacitor (DLCC) cells in sequence, including n diodes, n+1 energy storage inductors, and 2n energy storage capacitors.
