Harmonic mitigation has received much attention recently, and harmonic contribution evaluation is an important prerequisite. This paper proposes a harmonic source localization method based on critical admittance screening with the adjusted coefficient of determination, in order to determine whether the main contribution to PCC's harmonic voltage distortions is upstream or downstream. The data screening method is based on adjusted coefficients of determination according to the voltage and current data measured at the point of common coupling (PCC). Harmonic source localization is performed with critical admittance. Compared with the traditional harmonic source localization method, data segments with a high degree of linearity in the harmonic voltage and current of the PCC are selected based on the adjusted coefficients of determination. The effect of fluctuations in the background harmonic of the novel power system on the critical admittance is effectively circumvented, which improves the estimation accuracy of the harmonic admittance. In order to verify the performance of the proposed method, several scenarios with different properties of harmonic admittance have been designed in MATLAB. The verification demonstrates the validity and accuracy of the proposed method.","PeriodicalId":198086,"journal":{"name":"2022 Asian Conference on Frontiers of Power and Energy (ACFPE)","volume":"290 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115214321","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}

If this reserve capacity is not properly prepared, the power system may be in a dangerous state. In this paper, a day-ahead generation schedule of wind-thermal-storage system considering prediction error of wind power and load is proposed to ensure the security of this reserve capacity, as well as, which effectively coordinates the economy and safety of the day-ahead generation schedule. The actual value is regarded as the sum of the predicted value and its deviation for wind power and load in the proposed method. Among them, the predicted deviation is balanced and tracked by the automatic generation control (AGC) unit, and its output active power and reserved reserve capacity are modeled. What's more, the AGC has sufficient adjustable upper and lower limits to balance the electric power by applying constraints, and has the ability to track the fluctuation of the prediction deviation. Furthermore, since the prediction deviation is a random number, the model with random parameters is transformed into a deterministic model through a robust peer-to-peer model to verify the effect in the extreme scenario, as well as, a distributed energy storage device is introduced to promote wind power consumption and optimize the system operation economy. Finally, in an IEEE 30 node system, the background of high proportion of wind power connected to the power system is set, and the security and economy of reserve capacity under the extreme scenario are analyzed through the method proposed in this paper.","PeriodicalId":198086,"journal":{"name":"2022 Asian Conference on Frontiers of Power and Energy (ACFPE)","volume":"11 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123612645","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}

These factors should also be considered in long-term planning of the power system. Therefore, a source-grid-load-storage power system coordinated expansion planning model that considers demand response services is proposed in this paper. In this way, the ability to absorb large-scale renewable energy such as light and wind in the power system is improved. First, the power system operation model is proposed in this paper; secondly, the demand response services and electricity storage facility are modeled in detail; then demand response and electricity storage facility resources are used to alleviate the intermittent output of wind and solar power plants on the power side. A load-side demand response service planning model is proposed, and a source-network-load coordination planning model is proposed. Finally, the rationality of the model is verified through the analysis of simulation examples, and the advantages of the coordinated planning of source-grid-load-storage power system are proved. In addition, it can effectively guarantee the safety of power system operation and improve the absorption capacity of wind and light energy.","PeriodicalId":198086,"journal":{"name":"2022 Asian Conference on Frontiers of Power and Energy (ACFPE)","volume":"104 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127997062","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 order to make full use of the battery energy storage system to delay the upgrading and reconstruction of the distribution network, a comprehensive optimization method of selecting the site and capacity to participate in the peak load regulation of distribution network is proposed. In the proposed method, a bilevel planning model is built where the upper layer model is the capacity configuration model, which considers the investment income of DESSs and delaying the expansion and upgrade of the distribution network; whereas the lower layer model is the installation spot optimization model, which considers the characteristics and capacity limit of DESSs, and the load regulation for peak-load shifting. The validity of the proposed method is verified by the IEEE 33-bus system. Simulative results show that, the proposed comprehensive optimization method is suitable for different application scenarios with the integration of DESSs of different capacity configurations and different installation spots and can provide a technical support for the planning and managing of largescale DESSs accessing to the distribution network.","PeriodicalId":198086,"journal":{"name":"2022 Asian Conference on Frontiers of Power and Energy (ACFPE)","volume":"26 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125755639","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}
