However, the uncertainty of distributed renewable energy output brings high transaction risk to virtual power plant. For the VPP with renewable energy permeability, considering the uncertainty of renewable energy output, load and market price as well as the influence of demand-side resource participation in the power market, this paper puts forward the demand response bidding strategy of VPP under the open environment of electricity selling side. A multi-stage bidding strategy model is built for VPP participating in day-ahead energy market, intraday demand response market and real-time energy market, and solved based on stochastic programming theory.

Based on a preliminarily designed frame structure, optimization design based on tower structure and finite element analysis (FEA) is carried out. X-shaped crossbar structures and tilting supporting tubes are introduced as further reinforcement, besides dimensional and position parameters of the reinforcement structures are optimized with the assistance of FEA. FEA simulation results show that the first-order natural frequency of the supporting structure is optimized from 4.88 Hz to 10.02 Hz, while the incremental weight of the reinforcement structure is kept as low as 6.4 t.","PeriodicalId":250211,"journal":{"name":"Proceedings of the 2nd International Conference on Information Technologies and Electrical Engineering","volume":"58 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-12-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127690395","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 search ability of multi-random variable parameter optimization method is weak, and the search is assisted by particle swarm optimization. Considering that the particle swarm optimization algorithm is easy to fall into the local optimum and the existing problems of using the cross and cross algorithm to improve the particle swarm optimization algorithm, the vertical crossover operator based on the CSO re-improves the particle swarm optimization algorithm. According to the actual measured CVT harmonic transfer characteristic curve and the simulation results after optimizing the stray capacitance parameters, the accuracy of the multi-random variable parameter optimization method is verified. It provides a certain method basis for parameter optimization such as CVT stray capacitance and CVT harmonic correction for different models in the future.","PeriodicalId":250211,"journal":{"name":"Proceedings of the 2nd International Conference on Information Technologies and Electrical Engineering","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-12-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128706288","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}

{"title":"Reliability-Based Planning of Medium-Voltage Power Distribution Systems and a Sensitivity Study of SAIDI to the Key Parameters","authors":"Zhao Liu, Xiaoli Huang, Zongxiang Lu","doi":"10.1145/3386415.3387042","DOIUrl":"https://doi.org/10.1145/3386415.3387042","url":null,"abstract":"In the operation of a medium-voltage distribution system, any weakness in the system topology, facility reliability, technology application and interruption management can set a limit to the reliability indices. As the planning scheme of the distribution system is mostly formulated based on standards or guides, the influence of technology and interruption management on reliability is rarely considered at the planning stage. This can cause excessive investment to system construction and facility upgrades for meeting a reliability target. This paper introduces a practical approach for undertaking reliability-based planning for medium-voltage distribution systems, which is supplementary to the standard-based planning. The proposed approach enables optimisation strategies that cover system topology, facility, technology and interruption management to be formulated as part of the planning scheme. One of the key tasks in the reliability-based planning is to perform sensitivity study, which provides quantitative support to the formulation of optimisation strategies. This research focuses on five parameters, including the number of interconnected feeders, failure outage rate, number of feeders equipped with distributed automation, live-line working rate and scheduled outage rate. A sensitivity study of the system average interruption duration index (SAIDI) to these parameters is performed in order to assess the effectiveness of the corresponding improving measures. Results show that both strengthening the management of scheduled interruptions and enhancing the application of live-line working can be more effective than reinforcing the system topology when SAIDI is larger than 12 hours/customer. These two measures become less effective as SAIDI decreases. In contrast, reinforcing the system topology, increasing facility reliability and applying distribution automation techniques become increasingly effective as SAIDI decreases. When SAIDI is below 3 hours/customer, reinforcing the system topology becomes the most effective improving measure.","PeriodicalId":250211,"journal":{"name":"Proceedings of the 2nd International Conference on Information Technologies and Electrical Engineering","volume":"3 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-12-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123854721","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 independent control of positive and negative sequence active and reactive power, the global voltage regulation control of the device is realized while realizing reactive and negative sequence current compensation. A phase-injection voltage is applied between the phases to balance the phase-to-phase power and achieve phase-tophase voltage equalization.
