The control objective is to achieve satisfactory converter performance, facing not only variations in load resistance and renewable energy source voltage but also in the interaction of the individual converter in each stage. The intricate configuration nature of multi-stage cascaded boost converter renders the mathematical model complex, which is perplexing for the design methodology of controllers. In response to these challenging problems, the fuzzy controller can function without a precise mathematical model. It uses an understanding of the converter behavior to develop control rules that imitate human decision making. In addition to controlling the output voltage, the proposed fuzzy controller in this paper can manage the input current along with the reference current slope without overshooting or taking a long time to settle. The input current slope and the output voltage error are determined with suitable membership functions and their intervals. The fuzzy output is a change in duty, linguistically associated with the system inputs through 15 fuzzy rules. The simulations and experimental results indicate that the output voltage of 400 V is finely regulated with robustness. In addition, the results imply that performance performs effectively in both transient and steady states, even when the converter functions under conditions of fluctuating load resistance, input voltage, and desired output voltage.</p>","PeriodicalId":50546,"journal":{"name":"Electrical Engineering","volume":null,"pages":null},"PeriodicalIF":1.8,"publicationDate":"2024-08-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142185053","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The proposed approach initially analyzes dynamic changes in active and reactive power flow caused by a change in consumer power factor, followed by a loss allocation mechanism. This method is developed based on Kirchhoff’s law and the natural decomposition of injected bundled power flow at a bus. To completely eliminate cross-subsidies, the proposed mechanism follows a two-stage power flow: first, consumer-controlled power flows, and second, determining variations in power flow as compared to the first stage due to interactions with local generators. Consumer load modeling is being considered to improve the proposed method’s adaptability and efficiency across different distribution systems.

Existing literature typically formulates multi-objective problems to quantify the techno-economic assessment of DG placement in a distribution system. Nevertheless, there is a notable lack of a suitable method to assign weight impartially to each objective for optimal decision-making. This paper introduces a novel technique for strategically placing DG units in the distribution network, employing weights calculated based on the importance level of various techno-economic objectives using Shannon’s entropy. The proposed approach has been applied to a 38-node test system to illustrate its efficacy. The numerical findings from four distinct case studies reveal that changes in the physical attributes of the system correspondingly influence the significance of objectives in determining the optimal placement and size of DG. The results show significant reductions in active and reactive power losses and total annualized operational costs, with maximum reductions of 48.17%, 33.30%, and 42.96%, respectively.

Aiming at this problem, a scheme for preventing the maloperation of converter transformer saturation protection based on the waveform prediction of magnetizing inrush current is proposed. The proposed scheme utilizes the differences between the mathematical models of pure magnetizing inrush and magnetizing inrush superimposed with DC bias. Based on the mathematical analytical expression of magnetizing inrush current during the transformer unloaded energization, the complete waveform of the second cycle of phase current is predicted by using the actual measured values of the phase current within 1¼ cycles. The deviation between the predicted and measured peak values of the phase current of the second cycle is calculated. On this base, a modification coefficient is constructed to modify the measured current in the neutral line, which eliminates the influence of magnetizing inrush and prevents the maloperation of saturation protection.

This can include modeling the electrical characteristics of solar cells, as well as the interactions between multiple cells in a PV module. In ISIS-Proteus software, the existing research works have modeled the PV modules either by using a Proteus Spice model of the PV panel without including the effect of climatic conditions variation or by using pure mathematical relations that describe all physical and environmental parameters that lead to a static behavior. Therefore, this paper proposes a new improved ISIS-Proteus model of a PV cell/module for dynamic performance emulation under varying climatic conditions. The proposed model is designed based on the equivalent circuit of a five-parameter single-diode as an electrical part controlled by a numerical part that includes the mathematical expressions corresponding to each parameter. The designed model can capture the impact of solar irradiance and temperature on PV outputs, thereby enhancing real-world PV performance prediction. Also, it can effectively simulate the effect of the partial shading.

In this study, the simulation tests are carried out using ISIS-Proteus considering several PV module types and under various operating conditions, including uniform test conditions (UTCs) and partial shading conditions (PSCs).
