Both the respective modes of operation of the grid and the natural gas network are considered, as well as the application of coupling units and demand response. Nonlinearities in the operation of the energy network are handled by the piecewise linearization methods. Therefore, a mixed-integer linear planning (MILP) model is developed that can be efficiently solved by existing solvers. A case study of 26 electric nodes and 20 gas node systems is conducted to validate the effectiveness of the method. The case results show that the integrated demand response can reduce system cost and improve the load curve.","PeriodicalId":339798,"journal":{"name":"2020 IEEE 4th Conference on Energy Internet and Energy System Integration (EI2)","volume":"35 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-10-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115159872","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}

Especially in electricity markets, the randomness and variability of generation or load will cause notable forecast errors and lead to economic losses of market participants. Due to the data explosion in recent few years, data have gradually become valuable information that can be mined, analyzed, and applied. Meanwhile, the utility that more abundant and accurate information could eliminate uncertainty is emerging. In this paper, solar power plants (SPPs) are selected as the object, the general mechanism in electricity markets is briefly introduced and the corresponding market optimization model is constructed. With the optimization model analytically solved, the impact of uncertainty is analyzed and the expressions of information value are derived. Besides, uniform, normal, logistic, and Laplace distribution are used in the evaluation of information value and compared.

To ensure the voltage stability of the AC/DC distribution network, it is important to enlarge the load margin of ac/dc distribution network. By changing topology of the distribution network and adjusting control settings of DC links, the AC/DC distribution network may gain surpluses of the load margin without influencing the operations of distributed generators and loads connected. In this paper, a coupled optimization method is proposed to enlarge the load margin of the AC/DC distribution network, where both the topology reconfiguration and the regulation of control modes of voltage source converters (VSCs) are considered. The model of AC/DC power flow and continuous power flow (CPF) is introduced. Based on this, the optimization model for the enlarging load margin of ac/dc distribution network is presented. Then, the solving algorithm for the optimal problem is presented. Test results on a modified IEEE 33-node AC/DC hybrid system validate the effectiveness of the proposed method. Compared with optimization results using only topology reconfigurations or regulations control modes of VSCs, the load margin has been increased 14.4% and 3.8%.","PeriodicalId":339798,"journal":{"name":"2020 IEEE 4th Conference on Energy Internet and Energy System Integration (EI2)","volume":"245 11","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-10-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"120900192","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}

This paper proposes a fault location method for transmission grids based on the real-time synchronous measurement data of the Phasor Measurement Unit (PMU). The algorithm is based on the data measured by the PMU device. First, according to the measured real-time synchronous voltage and current data, the characteristic impedance and propagation coefficient of the line are solved online; the voltage and current data at both ends are used to perform equations on the voltage at the fault point. Column writing, through the equation relationship, and then solve the fault distance, realize the fault location function. Because there are certain errors in the process of measuring data, such as the asynchrony of the data at both ends and a certain low delay in the data communication process. To make the solved fault distance more accurate, in the synchronous measurement method, the method of data asynchronous fault 10-cation is proposed, the theoretical formula is derived, and the measurement error caused by the communication delay is analyzed in detail. At the same time, this paper uses PSACD software to build a model to verify the effectiveness and superiority of the method.","PeriodicalId":339798,"journal":{"name":"2020 IEEE 4th Conference on Energy Internet and Energy System Integration (EI2)","volume":"55 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-10-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125065838","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}

Many distribution systems are not observable due to their limited numbers of real-time meters, thus state estimation based approaches are not applicable. Moreover, the number of abnormal samples are usually small comparing to the diversity of anomalies, imposing challenges to machine learning based methods as well. To this end, AnoGAN, an unsupervised learning method, is applied to the distribution system anomaly detection in this paper. Only normal samples are needed during its training process. In the testing process, it generates corresponding samples based on its knowledge trained from normal ones, which are compared against real measurements to detect if there are possible anomalies. To achieve better granularity, we propose to partition a large distribution system into sub-networks, establish parallel AnoGANs, and employ Cross-stitch units to incorporate their correlations. Simulations have been done to show the satisfactory accuracy and efficiency of the proposed approach in detecting anomalies in distribution system.","PeriodicalId":339798,"journal":{"name":"2020 IEEE 4th Conference on Energy Internet and Energy System Integration (EI2)","volume":"14 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-10-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125081340","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}
