To maximize the profit of CHP units, an optimal generation bidding strategy for deep peak regulation ancillary service market is proposed. Firstly, the uncertainty of loads is modelled with the Latin hypercube sampling (LHS) method. Secondly, in order to obtain the period when CHP units obtain higher profits in deep peak regulation ancillary service market, the first stage dispatch model is established. Thirdly, queueing method is applied to clear the ancillary service market. Then the clearing amount and price of the market are used to determine the bidding capacities of CHP units in the market. Finally, the second stage dispatch model and algorithm are established to maximize the operating profit of the target units. The proposed model and techniques are validated through case study.","PeriodicalId":216155,"journal":{"name":"2021 International Conference on Power System Technology (POWERCON)","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2021-12-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126165486","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}

Renewable generators accrue along with the randomness and volatility of the generation side, therefore higher proportion of reserves are applied in the system for stability concerns. Zonal-partitioned reserve dispatch is commonly considered in large-scale reserve dispatch cases. This paper gives solution to energy-reserve joint dispatch problems concerning reserve cross-zone dispatchability by modified ADMM algorithm. The precision and economic-effectiveness of the algorithm is validated through case studies based on IEEE 30-bus system.","PeriodicalId":216155,"journal":{"name":"2021 International Conference on Power System Technology (POWERCON)","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2021-12-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129396469","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}

However, the DC series-parallel architecture will result in the power abandon, whose ultimate cause is that the operation states of wind turbines are different under different wind speeds. In order to analyze the correlation between wind speed characteristics and the power abandon in offshore wind farms with series-parallel architectures, a detailed analysis is presented in this paper. Moreover, the severity of power abandon is calculated through the case of a real wind farm, which will provide reference for the design and planning of offshore wind farms with series-parallel architectures in the future.","PeriodicalId":216155,"journal":{"name":"2021 International Conference on Power System Technology (POWERCON)","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2021-12-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128415092","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}

Especially when the homopolar inductor rotor was used in the HTS generator, it will also have a simple structure but high working speed which means powerful output capability. However, the design of HTS homopolar inductor alternator (HIA) rotor has to take multiple physics into consideration because of the complex working environment. The comprehensive but efficiency multi-physics predesign and multi-objective optimization of rotor parameters, which satisfies the limitation of electromagnetic output characteristics, magnetic distribution, strength, and rotor dynamics, are proposed. Finally, a prototype with the maximum output power of 30 kW is designed and manufactured, and the no-load experiment confirms the theoretical design. Meanwhile, the saturation issue is highlighted in the experimentation which will become increasingly obvious in the future miniaturization of HTS HIA.","PeriodicalId":216155,"journal":{"name":"2021 International Conference on Power System Technology (POWERCON)","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2021-12-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128484730","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}

One of the most crucial processes is to make the control decision table after a large amount of transient stability simulation. This process requires to be able to accurately distinguish between the transient (rotor angle) instability and short-term voltage instability. This paper proposes a fast shapelet learning method to extract features from the original voltage and rotor angle curves and then classify them through a machine learning (ML) model. Shapelet learning is a powerful data mining method, which can be used to extract hidden explainable information from power system time-domain simulation data. To overcome the huge time complexity of the shapelet transformation method, a genetic algorithm is applied to speed up the solution procedure. A case study is conducted on an 8-machine 36-bus system, and the simulation result indicates that the proposed method is with high explainability and fast learning speed.","PeriodicalId":216155,"journal":{"name":"2021 International Conference on Power System Technology (POWERCON)","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2021-12-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131090167","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}

Digital-analog hybrid simulation-- EMT model of large-scale power grid with physical control and protection devices has obvious advantages in studying the interaction between AC and DC. Based on the new generation of UHVAC/DC hybrid simulation platform in State Grid Simulation Center, a detailed EMT real-time simulation model of Southwest power grid in 2025 level year with voltage level of 110kV and above is built. In this model, 9 located HVDCs are simulated with 3 physical controllers and 6 digital control systems. Detailed simulation is carried out for the faults near the five DC transmission terminals in the centralized area. The AC and DC response in the process of faults and recovery are studied, and also the influence of commutation failure of one DC project on other DC systems. The results shows that AC faults in Panxi area doesn not have a serious impact on the concentrated DCs in the region. However, for the commutation failure of one DC circuit, the commutation failure of adjacent DC may occur at the same time due to the increase of sending terminal voltage.","PeriodicalId":216155,"journal":{"name":"2021 International Conference on Power System Technology (POWERCON)","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2021-12-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127635031","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}
