The selective harmonic elimination (SHE) method is considered for a single-phase 5-level cascaded H-bridge (CHB) inverter, in which the particle swarm optimization (PSO) algorithm solves the nonlinear equations. However, eliminating the low-order harmonics has been challenging when a low range of output voltage is required. To surmount such challenges and access to a wide range of output voltage, an adjustable dc-link is introduced that allows the inverter to increase the modulation index, resulting in a significant decrease in total harmonic distortion (THD). In this paper, to regulate the dc-link voltage amount, a 12-pulse rectifier is employed to allow the inverter to produce the output voltage requirements with less distortion. To prove such claims, the PSO algorithm is modified to calculate the optimal angles, as a result, the switching angles are applied in SIMULINK MATLAB to generate a 5-level output voltage.","PeriodicalId":392538,"journal":{"name":"2021 IEEE Kansas Power and Energy Conference (KPEC)","volume":"112 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-04-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132824680","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}

One of the challenges with analyzing large-scale electric grids is maintaining an understanding of the overall electric grid state, including the grid's flow pattern. The paper's algorithm addresses this by first aggregating the buses into groups. Then a Delaunay triangulation is used to create a planar graph, followed by a mapping of the transmission line flows onto this graph. Finally the flows are visualized with dynamically sized line thicknesses and/or flow arrows. Results are demonstrated using several example systems ranging in size from seven to 82,000 buses.","PeriodicalId":392538,"journal":{"name":"2021 IEEE Kansas Power and Energy Conference (KPEC)","volume":"6 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-04-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127865668","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 integration of these plants increases power reliability as well as permits challenges to the protection of the Power System. The fault characteristics of the converter-interfaced Renewable Energy Plant (REP) have conflict than conventional generators, the fault contribution is intermittent in nature, so the existing relay may fail to operate. And the REP's can be contributing the power demand in the duration of availability of sources of renewable energy, remaining time these plants turn out as load for maintenance servers, lighting and etc. Therefore, the relay located behind REP has to adaptable according to plant nature, to improve reliability and operation of grid integrated with renewable resources. Adaptive algorithms for Distance relay connected REP in the forward direction are scrutinized. The proposed Adaptive quadrilateral setting of the relay is to identify the fault direction and reverse the quadrilateral setting into third quadrant of the RX-plane if the fault occurs backside of the relay and provides the coordination with other relays which are protecting other feeders from the same bus.

Underground coal mining has less production and high output cost (cost per unit of coal production) due to the low effective utilization of equipment and also depends on geological conditions of the mine i.e. mine environment and condition of the roof. As the electrical energy cost for the coal mining industry is increasing every year, coal mining enterprises must conserve electrical energy for the reduction in output cost. In this paper, energy-use analysis has been performed to concept a benchmark for coal production at minimum specific energy consumption in an Indian underground coal mine. In preliminary inspection, different energy data are collected for major high energy consuming areas in the mining plant. A power balance chart of different equipment used in the mine has been prepared as per the working hours of equipment and demand factor of different equipment considering productivity norms to examine the shares of energy consumption. Results and major verdicts regarding energy cost reduction possibilities for several critical areas have been discussed to improve the energy-standard of the coal mine. This case study in an underground mining field scrutinizes the possible common energy-saving potential through detailed techno-economic analysis.","PeriodicalId":392538,"journal":{"name":"2021 IEEE Kansas Power and Energy Conference (KPEC)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-04-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129897418","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}

First, the mathematical models of governor systems in hydropower and thermal power generation units are presented, with secondary frequency control and Frequency Limit Control (FLC) considered. Then, the root locus method is used to study the frequency stability of the power system, and coordinated optimization between the secondary frequency control parameters and the FLC parameters addressed.

The Gyrator-Capacitor approach has been applied to model the magnetic circuit coupled with the electrical circuit.
