How to achieve the target model in a top-level design is an important issue in the construction of electricity market in China. Firstly, the differences and the similarities of these two models are analyzed based on foreign mainstream market models from four aspects: market decision making methods, market pricing methods, unit portfolios and auxiliary service transactions. Secondly, current situation of reform of electricity market in China is introduced. Based on grid structure and power supply structure in China, benefits of centralized market model in safe operation of grid, optimal allocation of resources and connection with existing dispatching system are analyzed; it is indicated that the proper Chinese electricity market model in the future is \"centralized spot market + medium-term and long-term difference contract\" model. The development of Chinese electricity spot market is forecast in three stages. Finally, the key technology demands in the construction of Chinese electricity market in the future are abstracted.","PeriodicalId":101544,"journal":{"name":"2020 Asia Energy and Electrical Engineering Symposium (AEEES)","volume":"39 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121831602","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 this paper, the mathematical model of the asynchronous wind turbine is established, and the power characteristics of the wind turbine are analyzed. On this basis, the effect of asynchronous wind turbine on the operation control of microgrid during the wind speed disturbance is analyzed. Furthermore, the microgrid operation control technology based on energy storage system is proposed, including the power circuit and its control strategies. Then a simulation model of microgrid including wind power generation is built by Matlab/Simulink, and the simulation verification under typical operating scenarios such as gust disturbance is carried out.

The high-power switching device such as IGBT used in the converter generates high slew rate current and voltage during the switching processes, and then the electromagnetic interference noise is propagated through the parasitic inductances and parasitic capacitances in the circuit. Therefore, the analytical model of high-power IGBTs is proposed in this paper to describe the switching transient characteristics, with the full consideration of parasitic inductances and parasitic capacitances of IGBTs.

In this method, the initial position of particles (i.e. the converter duty cycle in this paper) can be determined by a strategy, not random. When the photovoltaic (PV) string operates under PSC, the initial particles can ensure that the corresponding operating points work in the vicinity of the peaks. And under UIC, the initial position is close to the GP duty cycle by using the characteristic of DC-DC converter. Thus, the improved PSO maximum power point tracking (MPPT) method can reach the GP fast.

However, its application range is narrow currently, which is mainly limited by its low output power. The significance of this research is to explore the high output property of RV nuclear battery with high intensity energy sources. The material of energy conversion semiconductor unit is AlGaInP which conversion efficiency under 63Ni radioisotope sources are about 2%. The innovation is the using of average energy equivalent method, which equivalent radioisotope sources by adjusting the energy (50 keV, 62 keV, 66 keV, 80 keV, 100 keV, 150 keV) and the beam intensity (5×108, 1.5×109, 1×1010, 1×1011, and 1×1012 e/cm2•s) of the electron accelerator. Analyzing the output electrical property of series-parallel forms. With the increase of beam energy and intensity, the maximum output power shows a linear increase. The conversion efficiency of the RV nuclear battery is about 4%. Meanwhile, if the beam intensity is high, the surface of conversion units will have surface charge and discharge effect, and radiation damage effect leading to a reduction in conversion efficiency. The results prove that with the optimization of preparation process and the activity enhancement of radioisotope sources in the future, it can play main roles in more fields.","PeriodicalId":101544,"journal":{"name":"2020 Asia Energy and Electrical Engineering Symposium (AEEES)","volume":"68 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122291034","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 uncertainty of EV discharge response is characterized by fuzzy membership function, and the parting model of SOC initial value is established by probability theory, thus a hybrid opportunity-constrained programming model with both fuzzy and random parameters is constructed based on credibility measure.
