Two types of high pass filters are popular techniques for harmonic suppression, including second-order high pass filter and C-type filter. However, there is little research to reveal the characteristics of each filter. Designers have difficulties in choosing the optimal topology. Therefore, the paper provides a comprehensive analysis of the two high pass filters, especially the influence of system voltage on the filter cost, and summarizes their optimal application scenarios. The conclusion could be applied to power systems ranging from low voltage levels to high voltage levels, which helps solve the problem of filter topology selection and guides the design of filter packages.","PeriodicalId":118143,"journal":{"name":"2022 5th International Conference on Energy, Electrical and Power Engineering (CEEPE)","volume":"50 2","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-04-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132571963","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 the existing hydrogen market, the reforming of fossil fuels is the most mainstream way to produce hydrogen. Under the background that water electrolysis into hydrogen will become the mainstream method of hydrogen production in the future, the existing operation mechanism will no longer be applicable to hydrogen market. With the deepening of the coupling between both the electricity and hydrogen market, it is necessary to study the decomposition and coordination mechanism of the electricity-hydrogen market. In this paper, a joint clearing model for the electricity-hydrogen market is established. The above two markets are connected by power-to-hydrogen (P2H) and fuel cell facilities. A decentralized algorithm based on optimality condition decomposition (OCD) is developed to decompose and coordinate the electricity market and the hydrogen market. Case study based on modified IEEE-30 bus system with Belgian-20-node gas system demonstrate the effectiveness and efficiency of the proposed mechanism and method.","PeriodicalId":118143,"journal":{"name":"2022 5th International Conference on Energy, Electrical and Power Engineering (CEEPE)","volume":"29 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-04-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132909263","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, establish the calculation model of 'converting carbon by electricity', and calculate the conversion coefficient of 'carbon-electricity'; Secondly, data preprocessing methods such as isolated forest algorithm and exponential smoothing method are used to eliminate abnormal data, and then the processed 'carbon-electricity' conversion coefficient is input into the established BA-LSTM prediction model, and the prediction result of carbon emissions is obtained by combining with electricity consumption calculation. Finally, a verification analysis is carried out with the data of the whole society's electricity consumption and energy consumption in a certain province in China.

The traditional sequential scheduling module exposes serious problems. In order to solve these problems above, this paper establishes an integrated scheduling model, which determines unit reserve, base points (BPs) and participation factors (PFs) at the same time. It realizes the integrated decision-making of unit commitment (UC), economic dispatch (ED), and PFs of automatic generation control (AGC). To accurately capture the newly updated short-term wind power forecast, the finer time resolution is applied in the first few time intervals, such as 5, 15 and 30 min. Simultaneously, for the short-term wind power spike, energy storage system (ESS) as its countermeasure is used to deal with it. The entire model is regarded as a mixed integer linear programming (MILP) model, which is solved by CPLEX solver. The practicality and validity of the proposed model are verified by the IEEE-RTS system. In general, the integrated model proposed in this paper can accommodate more RES integration, relieve wind curtailment, reduce the total cost and improve the security of the power system, which has a wider application prospect in the power system scheduling field.","PeriodicalId":118143,"journal":{"name":"2022 5th International Conference on Energy, Electrical and Power Engineering (CEEPE)","volume":"122 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-04-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133859565","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 cross-regional market clearing method based on Locational Marginal Prices (LMP) and the flow-based (FB) model for cross-regional transmission capacity calculation are used for dynamic price zone partitioning and management. After considering the influence of geographical location and locational marginal electricity price, a k-means clustering model is used for price zone partitioning, and all transaction between price zones can be solved by FB model.

In order to reduce the adverse effects of high permeability of PV, the power system has put forward relevant requirements for PV to participate in peak and frequency modulation. A method to solve the problem of PV peak and frequency modulation is to use Flexible Power Point Tracking (FPPT) strategy which is photovoltaic power generation system (PVPGS) operates below the maximum Power Point, with active Power reserve. Most of FPPT strategies operates in the right-sides of Photovoltaic system, instead of the left-side. However, the right-sides operation mode has its defects, and the left-sides operation mode has its advantages. In this paper, the FPPT strategy of photovoltaic power generation system is classified and briefly described, and the tracking performance of FPPT strategy in different working conditions is studied, and its principles are analyzed, which provides a benchmark for researchers and engineers to choose suitable FPPT operation mode for specific applications. The simulation results show that the PVPGS is more stable when running on the left side of the photovoltaic characteristic curve, while it is difficult to give consideration to the corresponding dynamic speed and steady-state accuracy when running on the right side. The single-stage PV system have the problem of power reverse peak when running on the left side of the PV characteristic curve.","PeriodicalId":118143,"journal":{"name":"2022 5th International Conference on Energy, Electrical and Power Engineering (CEEPE)","volume":"21 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-04-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132410099","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}
