The internal model control has many advantages, such as intuitive design, strong practicability, simple structure, few on-line adjusting parameters and no need of accurate object model. Especially for the improvement of robustness and anti-interference and the control of the system with large time delay, the control effect is particularly significant. But the system model of internal model control is not easy to get, and it is difficult to get a more accurate internal model. In order to obtain a more accurate internal model, improve the control effect of the internal model control system and improve the dynamic characteristics of the control system, it is necessary to identify the model parameters of the controlled object efficiently. In this paper, the improved particle swarm optimization (PSO) algorithm is used to identify the system online and combined with the internal model control method to control the controlled object.","PeriodicalId":394287,"journal":{"name":"2020 5th International Conference on Power and Renewable Energy (ICPRE)","volume":"28 9 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-09-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130451966","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 weighted voltage is introduced as the key indicator for the proposed control and the steady voltage deviations are reduced significantly without changing the steady active power distribution. A MTDC grid with four-terminal VSCs is established in the PSCAD/EMTC software for the case study. Various severe fault conditions are taken account in the case study, including the outage of a constant power VSC and the outage of a droop VSC.

And it contains multiple ports of high-voltage DC, low-voltage DC, and low-voltage AC, which is convenient for various forms of load access and realizes plug-and-play function.

A dynamic power optimization strategy is proposed for microgrid based on the virtual synchronous generator’s frequency regulation characteristics in this paper. Load in microgrid is divided into planned load and unplanned load. The optimization model with the goals of minimizing the generation operation cost and the transmission power of the linking-up road is established to distribute the planned load. The genetic algorithm-simulated annealing algorithm is used to solve the optimization model. Active power generation plans for the VSGs are formulated in the light of calculation results. Central controller estimates the power fluctuation value when unplanned load fluctuations occur in the microgrid. VSG’s output power is dynamically adjusted based on the principle of equal marginal cost to achieve dynamic power optimization of microgrid.

As the core component of the equipment in these fields, the reliability of IGBT has always been an important research direction of power electronics. The existing research results show that the reliability of IGBT is closely related to its junction temperature change. How to estimate or measure the junction temperature of IGBT is the key point of its reliability research. Based on the need of reliability research, this paper proposes a junction temperature extraction method based on the turn-off losses, which uses the single loss Eoff in the process of IGBT turn off as the thermal sensitive parameter. In this paper, a non-contact state detection method is proposed, which uses the input and output voltage and current information of single inverter to predict the junction temperature without directly measuring the IGBT.
