Therefore, power system needs to consider the flexibility in planning stage. However, current flexibility metric is difficult to calculate and be applied in to the optimal planning. A non-sequential production simulation model with only input data of the cumulative probability function and/or probability density function of heat demand, electricity demand, and wind power is proposed, which is used to obtain the probability distribution of the production for generators according to least cost principle. Then the flexibility metric can be easily calculated based on the production results. Simulations were performed based on the actual data of a large wind power zone in north China. Multiple flexibility metric was evaluated and compared with the wind power curtailment, which shows the strong correlation between them. Finally, the impact of flexible resources on the flexibility metric was analyzed.","PeriodicalId":314015,"journal":{"name":"2021 11th International Conference on Power, Energy and Electrical Engineering (CPEEE)","volume":"142 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-02-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134217779","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}

Fuels are separately tested in each engine, the same engine specifications and test conditions. Results studied at speeds and full load on 200 hr show that RD mixed with ethanol and n-butanol had better engine performance and lower exhaust emissions than RD blended with other additives and RD baseline. Moreover, the results investigated at constant speed of 3,000 rpm and medium load on 500-hr engine test identify that they were similar to the results of 200-hr engine test. Engine wear results on 700 hr indicate that RD blended with ethanol and ethyl acetate had higher mechanical wear of engine parts than RD mixed with other additives and RD baseline. Especially, fuel injection pressure was reduced by 9% as compared with the engine's guide. Nevertheless, the mechanical wear results from using fuel blends were still acceptable since the engine wear by using fuels were within the specifications of engine's guide.","PeriodicalId":314015,"journal":{"name":"2021 11th International Conference on Power, Energy and Electrical Engineering (CPEEE)","volume":"134 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-02-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134106401","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 possible methodology for the monitoring of this parameter in transmission lines consists in the distribution of punctual temperature sensors along the line. This paper presents the development of electronic instrumentation for a current and temperature monitoring equipment to be applied in 230 kV power transmission lines. The chosen current transducer is the Rogowski Coil because of its linear response and decoupling between the measurement and power circuits, while the chosen temperature transducer is the NTC (Negative Temperature Coefficient) thermistor because of its low cost and high sensitivity. The developed prototype dos not use batteries or solar panels as power supply, as it is energized by the voltage induced in a secondary coil coupled to the transmission line. In order to increase the signal-to-noise ratio (SNR) and ensure electromagnetic compatibility (EMC), the hardware was developed and validated through numeric simulations and experimental measurements. Furthermore, digital noise reduction techniques such as oversampling and waveform averaging algorithms were implemented in the system. The developed equipment is theoretically able to measure electrical currents up to 1650 A, and was validated for currents up to 500 A and temperatures up to 90 °C. All collected data is transmitted to a computer for further analysis via wireless communication.","PeriodicalId":314015,"journal":{"name":"2021 11th International Conference on Power, Energy and Electrical Engineering (CPEEE)","volume":"27 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-02-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122482582","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}

At the same time, along with the large-scale promotion of electric vehicles (EVs), the disorderly access of charging load is bound to bring challenges to the safe and stable operation of the distribution network. Therefore, it is necessary to evaluate and analyse the impact of EV charging load access in the flexible distribution network. Firstly, this paper constructs operational constraints based on the operating characteristics of the flexible distribution network; secondly, based on the disorderly access characteristics of EVs, the EV charging load model is constructed through a multi-factor combination; finally, tests are carried out in the IEEE 33 interconnection system. The results show that the flexible interconnection can effectively optimize the distribution of tides over time and suppress the voltage deviation.","PeriodicalId":314015,"journal":{"name":"2021 11th International Conference on Power, Energy and Electrical Engineering (CPEEE)","volume":"77 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-02-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130307410","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}

DFIGs’ Low-frequency Damping Effects Based on Responses of Generic Component 基于通用部件响应的DFIGs低频阻尼效应

The controversial issue is hard to explain by traditional analytical tools like the modal analysis or MIMO methods, since their numerical results cannot provide fundamental physical significances about the coupling between DFIGs and the power system. Based on the idea of modular transfer-function modelling, the paper proposes a general theory named as rationales of \"responses of generic component (RGC)\", in order to have a complete explanation of potential damping effects induced by DFIGs (and other similar converter-interfaced generators) in intuitive frequency-domain forms. By using the complex torque coefficient method, the RGC-based rationales only rely on mathematical models and parameters of the DFIG, and thus are independent from the adjacent power systems. Analysis based on calculation of the DFIG’s RGC proves that, even if internal dynamics of the DFIG itself are poorly damped, DFIGs do not actively \"participate\" in electromechanical oscillations when in the normal maximum-power-tracking mode. In fact, only when additional active-power control like droop control is activated would the DFIG induce effective damping. Also, the proposed rationales clearly show the possibility of negative damping effects introduced by DFIGs. When a rudimentary power system is studied, observations and conclusions of both modal analysis and time-domain simulation could be well predicted by the RGC-based rationales.","PeriodicalId":314015,"journal":{"name":"2021 11th International Conference on Power, Energy and Electrical Engineering (CPEEE)","volume":"58 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-02-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115068132","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}
