First, three indicators are designed and used to establish a refined evaluation model of demand response potential based on users' historical electricity consumption data, and study the demand response potential of users and equipment under different economic incentives. Then the demand potential evaluation model is combined with the optimal scheduling model of load aggregators to obtain the optimal scheduling results. The simulation results show that the combination of this model and the optimal scheduling model of load aggregators can give full play to the demand response ability of users, improve user satisfaction, mobilize the enthusiasm of users, and thus improve the reliability and overall economy of load aggregators.","PeriodicalId":118234,"journal":{"name":"4th International Conference on Information Science, Electrical and Automation Engineering","volume":"39 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-08-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129418790","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, high performance permanent magnet synchronous motor control methods need to obtain accurate motor rotor speed and position information. However, high precision sensors are costly and prone to failure. Therefore, the speed sensorless control algorithm of permanent magnet synchronous motor is a hot topic for scholars. The existing speed sensorless control strategies are mainly observer methods based on the motor back EMF and algorithms based on the irrational characteristics of the motor. However, the observer method based on the motor back EMF is only suitable for the middle and high speed conditions of the motor. Although the algorithm based on the irrational characteristics of the motor can adapt to the low speed condition of the motor, it needs to continuously give additional excitation to the motor, the voltage utilization rate of the inverter is reduced, and the dynamic performance is not perfect. In this paper, the highfrequency injection method based on the irrational characteristics of the motor is used in the low speed condition, and the observer method based on the motor back electromotive force is used in the high speed condition, and the switching strategy is optimized to realize the speed sensorless control of the permanent magnet synchronous motor in a wider speed range. The simulation results show that, The composite control strategy adopted in this paper can accurately obtain the motor speed and rotor position information in a wider speed range, and the system runs well when the algorithm is switched.","PeriodicalId":118234,"journal":{"name":"4th International Conference on Information Science, Electrical and Automation Engineering","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-08-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"120965488","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}

Due to the UAV's dynamic constraints and the reconnaissance mission's specificity, the problem can be formulated as a special variant of the traveling salesman problem (TSP), called the dynamic-constrained TSP with neighborhoods (DCTSPN). To solve this problem, the authors propose a hierarchical algorithm based on deep reinforcement learning (DRL), divided into an optimal sequence planning layer and a shortest path planning layer. In the optimal sequence planning layer, Firstly, the neighborhood boundary of the target point is discretized to form multiple reconnaissance points; then, the complex trajectory planning problem is simplified to planning on a finite directed graph by randomly selecting a finite set of reconnaissance points from the neighborhood boundary of the target point set. The double deep Q network (DDQN) algorithm is used to solve for the target point traversal sequence and the reconnaissance points for each target. In the shortest path planning layer, Use the Deep Deterministic Policy Gradient (DDPG) algorithm to perform global path planning in continuous state space and action space and generate a dynamically feasible optimal flight trajectory under the guidance of the optimal reconnaissance sequence to complete the given reconnaissance mission, Avoid no-fly zones. The simulation results show that the hierarchical algorithm is highly applicable and efficient.","PeriodicalId":118234,"journal":{"name":"4th International Conference on Information Science, Electrical and Automation Engineering","volume":"30 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-08-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122406873","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, these works often consider the relationship between the provider and the recommended items as one-to-one or one-to-many, without considering the situation that each item may have multiple related individuals on the provider side. In this paper, we implement a two-sided fair perception recommendation method based on fair allocation in a context where the relationship pattern between providers and items is many-to-many relationship. Specifically, on the one hand, the attention of all consumers is considered as the total exposure available to the provider and is fairly allocated to each provider based on the fairness criterion, and on the other hand, each exposure of each item is allocated to each relevant provider based on the fairness criterion, and the sum of the exposure obtained by each provider in all relevant items is taken as its final exposure. We conducted experiments on a real-world dataset, and the results show that the approach in this paper provides better two-sided fairness compared to the benchmark approach while maintaining good recommendation quality.","PeriodicalId":118234,"journal":{"name":"4th International Conference on Information Science, Electrical and Automation Engineering","volume":"12 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-08-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126763504","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}
