Under the environment of supply side structural change and new electricity reform, how to coordinate the development of self-owned power plants and power grids faces new challenges. The judgment of the conditions for the participation of self-owned power plants in new energy consumption is an important prerequisite for the source-network interaction of the power plant. Therefore, this paper proposes a method based on SOM-Kmeans algorithm to judge the participation conditions of self-owned power plants in the interactive scene of new energy consumption. Firstly, based on the daily wind speed and illumination intensity data within a year, the sunrise force data of fans and photovoltaic power generation units are obtained through the new energy output model. Secondly, the new energy output scenes are clustered and cut, and the typical new energy output scenes are obtained based on the SOM-Kmeans algorithm. Finally, the typical output scenes are analyzed, and the response quantity and response time conditions of the self-supplied power plant are judged by combining the day-ahead generation plan data of the self-supplied power plant.","PeriodicalId":187017,"journal":{"name":"2022 4th International Conference on Electrical Engineering and Control Technologies (CEECT)","volume":"95 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123533494","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 monitor and warn sub-synchronous oscillations when they occur and avoid further escalation of accidents, it is urgent to carry out wide-area monitoring for SSO. Therefore, a sub-synchronous oscillation identification method based on Extreme Learning Machine (ELM) is proposed in this paper. Through the analysis and observation of PMU signal waveform images, this paper found that SSO can be identified from three aspects: the trend of PMU signal waveform, the fluctuation of envelope and the length of stationary subsequence. Thus, the SSO identification problem can be transformed into a Classification problem. In this paper, the classical ELM algorithm is adopted to realize the fast and accurate recognition of SSO. The proposed method is verified in detail by the synthetic signal, and compared with the Support Vector Machines (SVM) algorithm. The results show that the proposed method can effectively identify SSO even in the case of large noise. Therefore, the theoretical results are expected to provide technical support for SSO real-time warning in the future.","PeriodicalId":187017,"journal":{"name":"2022 4th International Conference on Electrical Engineering and Control Technologies (CEECT)","volume":"10 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126015411","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 addresses the multistage dynamic feeder capacity enhancement planning problem of a distribution system where PV and energy storage systems (ESS) are jointly integrated, and a novel comprehensive planning method based on geographic constraints of distributed renewables is proposed. In this process, load growth and the development of PV and ESS limited by spatial capacity saturation are taken into account. At each planning stage, the operation conditions are divided into several typical day scenarios clustered from the history data. Accordingly, the underlying idea of dynamic programming is used to obtain an optimal solution. The object is to maximize the PV consumption rate. As constraints, the bus voltage, feeder power flow, charge and discharge power of ESS should be maintained within the standard level. Numerical results of an actual distribution system illustrate the effective performance of the proposed approach, and the power supply reliability improvement brought about by planning is also analyzed.","PeriodicalId":187017,"journal":{"name":"2022 4th International Conference on Electrical Engineering and Control Technologies (CEECT)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129323426","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 consumption of energy and cooling water of CO2 compression process are the key reason for the high operating and construction costs of carbon capture and storage systems. Aiming at reducing the cost, this paper proposes a solar-driven organic rankine cycle system coupled with carbon compression cooling process for low-temperature waste heat utilization, called the ORC-CCC. It can effectively reduce the amount of cooling water and compensate for the energy consumption of the CO2 compression process. On the other hand, the cascaded and coupled energy utilization measures cause complex multivariable coupling and strong nonlinearity in the ORC-CCC dynamics and thus it is difficult to control it well. Therefore, based on the mathematical analysis on variable coupling characteristics of the ORC-CCC dynamic simulation system which we have built, a novel multivariable active disturbance rejection controller with a feedforward compensator (MADRC-FF) according to the coupling characteristics is proposed, and genetic algorithms is used to optimize the controller parameters. Since the MADRC- FF is more complex in structure compared with the traditional decentralized active disturbance rejection control, this paper theoretically proves its stability, feasibility and decoupling ability. The simulation verified its validity and better performance in multivariable control.","PeriodicalId":187017,"journal":{"name":"2022 4th International Conference on Electrical Engineering and Control Technologies (CEECT)","volume":"25 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127054287","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}

Using the composite load model (CLM) as the model structure, parameter identification is a major challenge in load modeling. Measurement-based parameter identification of CLM can be expressed as a complex optimization problem with differential-algebraic equations (DAEs)-based dynamic constraints. Conventional population-based evolutionary programming algorithms are computationally intensive as the fitness evaluation has to be carried out exhaustively for all the individuals. To enhance the computation efficiency in load modelling. In this paper, Bayesian optimization is proposed. Case studies are presented to demonstrate the effectiveness of the proposed Bayesian optimization method. Comparing with the conventional particle swarm optimization, the proposed Bayesian optimization can significantly reduce the computation time as fewer times of time-domain simulation-based fitness evaluation is needed. But both algorithms can achieve similar performance on the estimation accuracy.","PeriodicalId":187017,"journal":{"name":"2022 4th International Conference on Electrical Engineering and Control Technologies (CEECT)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130004898","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 solve the problems mentioned above, this paper proposes a power coordinated control method based on energy-storage parallel compensator. Considering both the state of charge (SOC) of the energy-storage battery and the device capacity limitation, the parallel compensator under proposed control method performs real-time active and reactive power compensation to the grid, effectively solving the power fluctuation of the grid-connected system and ensuring the stability of the common coupling point voltage. The overall performance of the proposed control method is illustrated with the four-quadrant operation principle, the coordination control method mechanism, and the simulation-based performance. Finally, based on RT-BOX hardware-in-the-loop experimental platform, the experimental verification of different working conditions is carried out.

Generally, a pressure relief valve is installed to respond to a spike in oil pressure. In recent years, even equipped with pressure relief valves, transformers have regularly been engaged in igniting and explosion mishaps caused by internal arcing faults, which have raised concerns about the reliability of the protection. For a long time, due to the lack of corresponding numerical calculation model and detailed test data, the industry is uncertain about the transient operation characteristics of the pressure relief valve.
