However, the uncertainty of RE will cause electrical system interruptions, excess energy output, and a lack of electricity supply. Energy storage systems (ESSs) can be used to solve supply problems, but they should consider the reliability component of the power system. It is important to assess the impact of RE incorporated ESS for reliability studies. Optimal allocation of RE incorporating ESS needs to be tackled to ensure the grid failures and their impacts. This research shows the optimal allocation of RE with ESSs for power system reliability. The Force Outage Rate (FOR) for the energy storage system, photovoltaic system, and weather conditions was obtained from the development of each Markov model. Then, each FOR is combined to get the new FOR. The value of LOLE must be below 0.1 per year or 2.4 hours per year and the value of EUE should close to zero. Accordingly, this paper shows that the optimal allocation of PV incorporating ESS that minimizes the LOLE and EUE while satisfying the installation target and constraints on reliability indices.","PeriodicalId":297829,"journal":{"name":"2023 IEEE 3rd International Conference in Power Engineering Applications (ICPEA)","volume":"30 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-03-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130225589","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 regard, Frequency response analysis (FRA) is a favourable tool that can be used to detect a such fault. The FRA method has four measurement configurations called: end-to-end; open circuit test, short circuit test, and inductive inter-winding test, capacitive inter-winding test. However, a method of detecting the short circuit fault using FRA end-to-end measurement is investigated. This paper aims on investigating the inductive inter-winding of short circuit faults by showing a bipolar signature. The FRA inductive inter-winding measurement has been obtained from 11/0.415 kV, 500kVA distribution transformer to interpret the characteristics of resonances indicating a bipolar signature. There is a different level of short circuit fault artificially applied to the transformer winding. The inductive inter-winding measurements show that the resonances showing the bipolar signature at the mid-frequency range can be employed to determine the short circuit fault in the transformer winding. Based on this finding, a process of identifying the short circuit fault of a transformer winding is proposed. The data of short circuit fault and normal data of FRA measurement are compared. The proposed method can add to improving the purpose of using the FRA method to detect short-circuit faults in power transformers.","PeriodicalId":297829,"journal":{"name":"2023 IEEE 3rd International Conference in Power Engineering Applications (ICPEA)","volume":"2 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-03-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134116299","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}

For example, the signal components to be removed include the interference signals from power lines. Such unwanted frequencies are called notch frequencies, and notch filters play the central role in removing the unwanted signal components. Ideally, the magnitude response of a notch filter at notch-frequency (NF) should be zero. To implement a notch filter with a recursive structure, it is mandatory to guarantee its stability. Otherwise, the notch filter becomes useless. A useful technique is presented in this paper for guaranteeing the stability of a recursive variable NF filter. By employing this stability-guarantee technique, a notch filter can be designed with a recursive structure, and its stability is absolutely ensured. This stability-guarantee technique is derived from the well-known stability-triangle condition, and it utilizes parameter transformations. After showing the stability-guarantee technique, we apply it to the design of a digital notch filter whose NF is variable. This illustrative example not only verifies the guaranteed stability, but also demonstrates the high design accuracy.","PeriodicalId":297829,"journal":{"name":"2023 IEEE 3rd International Conference in Power Engineering Applications (ICPEA)","volume":"78 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-03-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126059202","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 unexpected power generation outages lead to a severe damage in one or more of the power components. This damage requires immediate scheduling of the available generation units to minimize the risks and increase the system security. This paper presents an optimization technique of load curtailment to be immediately applied in case of power generation outages. The optimization method involves a prompt response of the generation outages through predefined variables and constraints. The objective function of the proposed technique takes into account the power dispatch cost and the compensation cost, which will be paid directly to the end-user customers as a reward for their contribution of curtailing some of their loads. The amount of the power dispatch and the load curtailment are precisely evaluated using Mixed-Integer Linear Programming, where all the possible variables are tested before reaching a feasible solution. Example studies are presented to explore the performance of the load curtailment and to schedule all the energy sources during stochastic scenarios of the generation outages.","PeriodicalId":297829,"journal":{"name":"2023 IEEE 3rd International Conference in Power Engineering Applications (ICPEA)","volume":"3 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-03-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127933123","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 fuzzy analytic hierarchy process (FAHP) and technique for ordering preference by similarity to an ideal solution (TOPSIS) are both used in this work. Before figuring out the selected feeder’s rank using TOPSIS, each criterion’s weight must first be figured out using FAHP.

This method is based on the principle of decision-making analysis combining qualitative and quantitative analysis of multi- objective complex problems. The weight of indexes at all levels are calculated by the judgment matrix. After the consistency test, the overall judgment matrix is calculated to select the best scheme, which achieves the effect of decomposing and analyzing the communication network of distribution network. Through the analysis of 5 kinds of communication networks, namely optical fiber communication network, 4G network, 5G network, wireless private network and power line carrier, this research constructs the AHP model with accessibility, coverage, economy, reliability and security as the main parameter indexes, and obtains that 5G is the optimal scheme with 26.0178% of the comprehensive weight.

Nevertheless, high-voltage cable insulation cannot be extruded from PP because it is stiffer than XLPE. When compared to XLPE, PP has a lower thermal conductivity at room temperature, which would normally lead to poorer dielectric characteristics. As a result, PP needs to be changed in order to change both its physical and electrical properties. This investigation suggested PP and ethylene-propylene-diene monomer (EPDM) to be blended to create a PP blend with less overall stiffness. The work included characterizing the structure and the thermal behavior of the raw materials including PP, EPDM, and magnesium oxide (MgO). Several investigations involving thermogravimetric analysis (TGA), Fourier transform infrared spectroscopy (FTIR), and differential scanning calorimetry (DSC) were used to characterize the PP, EPDM, and MgO.
