Under these trends, studying how to enable electricity retailer to solve the problem of renewable energy consumption in the context of the spot market is a key element in building a diversified, open and competitive electricity retail market. This paper presents an optimization method of retail packages for electricity retailers considering the spot market environment and the consumption of renewable energy. After analyzing the characteristics of the electric spot market and the value of electric energy under the goal of carbon peak and carbon neutrality, firstly, the clustering algorithm is used to quantify and classify the load characteristics of users, then, the behavior of users choosing packages is studied through user utility to ensure that the user's choice is consistent with the expectations of the electricity retailers, and an optimization model of packages with the goal of maximizing the profit of the electricity retailers is established after introducing the spot market and renewable energy. The calculation example obtains configuration plan of the green retail package suitable for different users with the data set in a certain city, which provides a scientific basis for the design and optimization of the retail packages for electricity retailers under the current national policy guidance.","PeriodicalId":136285,"journal":{"name":"2021 IEEE 4th International Conference on Renewable Energy and Power Engineering (REPE)","volume":"13 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-10-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129732366","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}

QDIBSC can produce high efficiency by utilizing photons having energy lower than the bandgap energy of absorber material. Power conversion efficiency (PCE) of QDIBSC depends on intermediate bands (IBs) position and width. IBs number, position and width again depend on quantum dot (QD) size, barrier material content, interdot distance. In this numerical analysis to illustrate the position, number and width of the IBs were determined by resolving the time-independent Schrödinger wave equation with the help of the Kronig-Penney model. In this part of work, the effect of multi IBs on PCE of InAs0.9sN0.02/AlPxSb(1-x) QDIBSC was theoretically investigated and maximum efficiency was found to be 63.12% for three IBs, 51.91% for two IBs and 3S.SS% for the single intermediate band for a certain QD size, phosphorus content and interdot distance.","PeriodicalId":136285,"journal":{"name":"2021 IEEE 4th International Conference on Renewable Energy and Power Engineering (REPE)","volume":"146 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-10-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134343221","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}

It presents itself as a promising alternative for supplying national electric demand. In order to develop a photovoltaic system, it is very important to know how solar resource behaves in a given place and its variability during the year. The objective of this study was to obtain data from a given number of solarimetric stations and to compare it with satellite data from the same places, analyzing the differences observed in order to assess its influence in the risks of the decision to construct a photovoltaic generation system. It was concluded that irradiation models presented high correlation coefficients with the typical meteorological year, higher than 0.90 for the less accurate and higher than 0.98 for the more accurate. Student's t test presented probability higher than 97% of the results to correspond to reality. Another conclusion indicates that models with higher correlation coefficient can be used in feasibility studies for decision making, with uncertainties smaller than measurement errors.","PeriodicalId":136285,"journal":{"name":"2021 IEEE 4th International Conference on Renewable Energy and Power Engineering (REPE)","volume":"64 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-10-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124889449","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}

Its efficient storage and accurate retrieval play an important guiding role in the operation evaluation and supervision management of power grid equipment. This paper takes the power grid equipment maintenance, defects, alarms and oil chromatography, etc. as the research object, and proposes a top-down and bottom-up method to build a knowledge graph of power grid supervision business, which assists supervision management personnel to grasp the status of equipment in a timely manner and improve the power grid's emergency handling capabilities. Firstly, the schema layer is defined, including knowledge entities and relations between entities from top-down; then, the data layer from bottom-up is constructed through the rule-based template extraction and intelligent model-based approach; besides, the trinomial tree model is used to achieve multi-source data fusion, with a matching rate of 95.33% and an error rate of 2.3%; finally, the Neo4j graph database is applied to store and visualize the power grid supervision business knowledge graph. Also, the application of the knowledge graph is analyzed, including intelligent information retrieval and equipment condition evaluation and prediction. Through the case study of the oil chromatography data evaluation, the effectiveness of the above-mentioned knowledge graph is verified.","PeriodicalId":136285,"journal":{"name":"2021 IEEE 4th International Conference on Renewable Energy and Power Engineering (REPE)","volume":"100 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-10-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131799432","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}
