First, the virtual controller module is designed by coupling AC frequency and active power through virtual inertia control, so that the VSC-MTDC system can provide inertia response for AC grid frequency. Second, by introducing the power margin of the converter station into the droop coeﬃcient, the unbalanced power on the DC side is reasonably allocated to reduce the overshoot of the DC voltage in the regulation process. Finally, the power regulation capability of the normal AC system is used to provide power support to the fault end system, reducing frequency deviations and enabling inter-regional resource complementation. The simulation model of the three-terminal ﬂexible DC grid is built in PSCAD/EMTDC, and the eﬀectiveness of the proposed control strategy is veriﬁed by comparing the conventional control strategy and the additional frequency control strategy.","PeriodicalId":45464,"journal":{"name":"Archives of Electrical Engineering","volume":null,"pages":null},"PeriodicalIF":1.3,"publicationDate":"2023-12-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"138592274","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}

In this study, we construct a simulation model for composite insulator contaminant deposition using the COMSOL simulation software, and the rationality of the simulation model and method is veriﬁed through wind tunnel experiments. Taking the FXBW4-110/100 composite insulator as an example, we adopt a progressive optimization plan to explore the impacts of shed spacing 𝑠 , and shed inclination angles 𝛼 and 𝛽 on its contaminant deposition characteristics under DC and AC voltages. Based on the numerical simulation results, we analyze the antifouling performance of insulators before and after structural optimization. The results indicate the following: 1) The contaminant deposition of the insulator under AC and DC voltages is negatively correlated with the shed spacing 𝑠 , but positively correlated with the lower inclination angle 𝛽 . 2) Under AC voltages, the contaminant deposition of the insulator increases with the upper inclination angle 𝛼 , while under DC voltages, the contaminant deposition shows an uptrend ﬁrst, then a downtrend and then an uptrend again with the increase of the upper inclination angle 𝛼 . 3) Compared with the original model, the AC-optimized model ( 𝛼 = 6 ◦ , 𝛽 = 2 ◦ and 𝑠 = 98 mm) with a larger shed spacing 𝑠 , and smaller shed inclination angles 𝛼 and 𝛽 showed superior antifouling performance at wind speeds of no less than 2 m/s, and under the typical conditions ( 𝑣 = 2 . 5 m/s, 𝑑 = 20 μ m, and 𝜌 = 2200 kg/m 3 ), its contaminant deposition is 15% less than that of the original model ( 𝛼 = 10 ◦ , 𝛽 = 2 ◦ and 𝑠 = 80 mm).","PeriodicalId":45464,"journal":{"name":"Archives of Electrical Engineering","volume":null,"pages":null},"PeriodicalIF":1.3,"publicationDate":"2023-12-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"138593583","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 objectives are to minimise active power loss while considering the reduction of reactive power loss and total bus voltage deviation, and the maximisation of the voltage stability index. The proposed HB algorithm has been tested on a modiﬁed IEEE 33-bus AMG under four scenarios of the load proﬁle at 40%, 60%, 80%, and 100% of the rated load. The analysis of the results indicates that Scenario 4, where the HB algorithm is used to optimise droop gains, the positioning of DDGs, and their reference voltage magnitudes within a permissible range, is more eﬀective in mitigating transmission line losses than the other scenarios. Speciﬁcally, the active and reactive power losses in Scenario 4 with the HB algorithm are only 0.184% and 0.271% of the total investigated load demands, respectively. Compared to the base scenario (rated load), Scenario 4 using the HB algorithmalsoreducesactiveandreactivepowerlossesby41.86%and31.54%,respectively. Furthermore, the proposed HB algorithm outperforms the diﬀerential evolution algorithm when comparing power losses for scenarios at the total investigated load and the rated load.

The combined eﬀect of copper losses, core losses, and mechanical losses results in IM power losses. Unfortunately, the core losses in the motor, which have a considerable impact on its energy eﬃciency, are not taken into account by the generally employed dynamic model in the majority of the studies. Due to this, the motor rating often corresponds to the worst-case load in applications, but the motor frequently operates below rated conditions. A hybridized model reference adaptive system (MRAS) with sliding mode control (SMC) is used in this study for sensorless speed control of an induction motor with core loss, allowing the motor to operate under a variety of load conditions. As a result, the machine can run at maximum eﬃciency while carrying its rated load. By adjusting the 𝛼 -axis current in the 𝛼 − 𝛽 reference frame in vector-controlled drives, the system’s performance is enhanced by running the motor at its optimum ﬂux. Regarding the torque and speed of both induction motors with and without core loss, the Adaptive Observer Sliding Mode Control (AOSMC) has been constructed and simulated in this case. The AOSMC with core loss produced good performance when the proposed controller was tested.","PeriodicalId":45464,"journal":{"name":"Archives of Electrical Engineering","volume":null,"pages":null},"PeriodicalIF":1.3,"publicationDate":"2023-12-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"138591451","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}
