In the presence of network attacks, distributed generators (DGs) may experience partial loss of effectiveness (PLOE) and bias faults in their actuators. These fault parameters can be heterogeneous and time-varying, posing significant challenges to voltage regulation. To address this, our approach incorporates adaptive techniques to handle the fault parameters while avoiding their direct dependence. Furthermore, we utilize boundary layers to design smooth controllers that mitigate the adverse effects of non-smooth controllers, ensuring stable and precise voltage regulation. Through extensive simulations, we validate the effectiveness of our proposed strategy in achieving reliable and robust load voltage regulation in AC MGs.","PeriodicalId":391372,"journal":{"name":"2022 First International Conference on Cyber-Energy Systems and Intelligent Energy (ICCSIE)","volume":"104 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-01-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124045884","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}

Through the analysis of the power flow calculation errors, it was found that the main reason for the errors is that the actual transformer loss cannot be truly calculated based on the mechanism model of transformer under the condition of three-phase unbalance. On basis of the historical operation data in the distribution network, a data and mechanism fusion modeling method is adopted, and the mechanism model is used to guide the establishing of the data model. Firstly, grey relational analysis is used to select the key feature variables for the soft sensing model of transformer loss. Meanwhile, combined with the Tent-SSABP algorithm, the soft sensing model of the transformer loss value is established. Then, it is embedded into the three-phase power flow algorithm to replace the mechanism model of transformer, and a data-mechanism fusion power flow calculation has been achieved. Finally, the power flow calculation method proposed is verified in an actual research projection. The results show that the proposed method has higher accuracy than the traditional power flow algorithm using the mechanism model of transformer.","PeriodicalId":391372,"journal":{"name":"2022 First International Conference on Cyber-Energy Systems and Intelligent Energy (ICCSIE)","volume":"3 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-01-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124548638","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}

To achieve foresaid aims for permanent magnet synchronous motors providing energy to fan-pump load, this paper proposes a starting strategy of speed open-loop-current closed-loop control with current-frequency ratio in low speed section. Firstly, the rotor position is estimated by Lumberg observer in middle and high speed section, and the vector control method of speed-current double closed-loop is switched. Secondly, the starting process of current-frequency ratio speed open-loop and current closed-loop is studied, and the conditions of stable starting and acceleration are given. Thirdly, a state switching strategy of open-loop algorithm and closed-loop algorithm is proposed to ensure that the torque does not change abruptly during the switching process. Furthermore, a method of rotor stalling detection based on back EMF calibration is proposed, which detects the stalling state of rotor during buffeting. Moreover, the design rule of the PI parameter of the current loop in vector control is derived. Eventually, the experiment results verify the proposed method performance.","PeriodicalId":391372,"journal":{"name":"2022 First International Conference on Cyber-Energy Systems and Intelligent Energy (ICCSIE)","volume":"15 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-01-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131852902","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 order to ensure the safe and reliable operation of the power grid, it is necessary to solve the problem of splitting caused by the information physical failure of power grid and information network. First, a Cloud-Station collaborative information transmission framework is proposed. The distributed information transmission mechanism under the information transmission framework is described. The advantages of the above framework in dealing with power grid information failures are analyzed. Then, an active splitting strategy is proposed for power system with flexible switches under severe faults (including optical fiber communication interruption) of power grid by the improved spectral-clustering algorithm. When the power grid is splitting, the flexible switch is put into operation and controls the power flow to balance between the disconnected subsystems. The improved strategy considers the basic constraint, while adds the connection constraint of flexible switch and the modification of generator homology constraint to the operator. It can realize stability of the system after splitting in frequence and voltage, to ensure the transient stability of the power grid which facilitating the restoration of the power grid after faults. The above models are constructed in PSCAD for simulation, and the simulation results shows that the algorithm proposed in this paper is efficient.","PeriodicalId":391372,"journal":{"name":"2022 First International Conference on Cyber-Energy Systems and Intelligent Energy (ICCSIE)","volume":"30 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-01-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124962800","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 energy transformation is currently a social issue of global concern, and the focus is on the power industry to vigorously develop clean energy. Hydropower is the most mature renewable energy source and has been in a priority position in the energy mix. In this paper, we propose a decomposition and parallel calculation method to optimize the operation of medium and long-term cascaded hydropower units. Firstly, a model for optimal scheduling of cascaded hydropower units is established. Then, the model is decoupled in time based on the augmented Lagrangian relaxation. And the diagonal quadratic approximation method is introduced to ensure the decomposability of the decoupled problem so that the subproblems can be computed in parallel. In addition, an arithmetic analysis is performed with actual data to verify the effectiveness of the proposed method.","PeriodicalId":391372,"journal":{"name":"2022 First International Conference on Cyber-Energy Systems and Intelligent Energy (ICCSIE)","volume":"5 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-01-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122127128","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}

By introducing a framework for the synergistic use of carbon capture power plants (CCPP) and P2G equipment, the high concentration of carbon dioxide (CO2) captured is used as feedstock for P2G equipment, and a Carbon Storage Device (CSD) is proposed to solve the time mismatch between the capture and use of CO2.
