During the testing process, quench protection (QP) is indispensable for protecting the load from being overheated damaged. In this paper, a compatible and flexible QP framework is put forward to meet the different QP requirements including transferring time, protection voltage, the temperature raise, current decay speed and so on. The QP framework can provide the solution of changing the power units parameter on account of specific testing superconducting magnet. Firstly, the LSTF is introduced and the QP process in the system is comprehensively analyzed by discussing the power units’ actions and circuits currents’ flowing. Then the power units of QP system are studied by elaborating the power parameters adjustments in corresponding to different loads, especially the counter-pulse capacitor unit and the fast discharge resistor system. Finally, the testing process of central solenoid coil used for the China Fusion Engineering Test Reactor is described to illustrate the operation of the QP framework.","PeriodicalId":223198,"journal":{"name":"2020 5th Asia Conference on Power and Electrical Engineering (ACPEE)","volume":"6 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131576819","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 a centralized electricity market, market participants must pay a certain amount of guarantee money to protect credit and avoid failure to perform the contract due to various reasons. Although most provinces in China have carried out electricity transaction, but existing credit management system is still in the part of credit evaluation, and the trading risk inspection is insufficient. Thus, it is difficult to form an effective incentive and punishment mechanism for dishonesty. Therefore, it is necessary to establish a relatively perfect credit risk management system which is matched with the construction of China's power market. This paper introduces the theory of credit management and risk assessment in the electricity market, and puts forward the calculation methods of credit limit and tradable electricity limit. Based on credit management rules of Guangdong electricity market, this paper calculates the performance risk of a market participant and the corresponding amount of performance guarantees. Based on the theory and case, this paper analyzes the problems that need to be solved in the current credit and risk management, and points out that settlement risk is closely related to the transaction cycle, price fluctuation, invoicing and settlement time of related transactions. The calculation of market risk needs to take into account the situation of all transactions. More flexible ways such as commercial insurance to standardize financial products to provide mortgage credit guarantee have to be explored. At the same time, a more standardized credit rating method combined with the tangible assets of the market participant is to be established, to estimate the unsecured credit more accurately, and to provide a more relaxed and reasonable trading space for the participant with good credit.","PeriodicalId":223198,"journal":{"name":"2020 5th Asia Conference on Power and Electrical Engineering (ACPEE)","volume":"53 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131752469","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 problem of joint output dispatching of multiple clean energy power generations connected to the grid at the same time needs to be solved urgently. Considering that Concentrating Solar Power(CSP) has good dispatchability and controllability, it can be used as a dispatching measure to suppress the random fluctuations caused by grid-connected wind power and improve the utilization rate of wind power. A combination of Wind power-Photovoltaic power-Thermal power-Concentrating Solar Power is proposed. Joint optimal scheduling model of clean energy considering CSP regulation. This model stabilizes the fluctuations caused by the wind power and photovoltaic power grid connection by changing the thermal storage / exothermic heat generation time of the CSP and adjusting the thermal power output power, and improves the wind power and photovoltaic power utilization rate, making the joint output more stable, but the scheduling measures cannot be unlimited due to cost constraints. To regulate. In order to make the joint output after scheduling both stable and economical, this paper sets the joint output optimization scheduling model with the goals of the lowest comprehensive dispatch cost and the smallest joint output power variance, and solves it with differential evolution for multiobjective optimization algorithm(DEMO). The pareto-optimal set is calculated based on the fuzzy membership function. The satisfaction of the optimal solution concentrates the decision vector, and the one with the highest satisfaction is the optimal compromise solution. Finally, an example simulation calculation was performed using a power grid in northwest China. The results show that the proposed joint optimal scheduling model can effectively improve the grid-connected utilization rate of wind power, and the combined output power is stable and the dispatching cost is economic.","PeriodicalId":223198,"journal":{"name":"2020 5th Asia Conference on Power and Electrical Engineering (ACPEE)","volume":"36 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132682919","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}
