To capture the uncertainties, a stochastic day-ahead optimal scheduling model of an ADN is proposed to minimize power losses and voltage deviations in this paper. First, a deterministic day-ahead optimal scheduling model of an ADN is formulated given a series of operational constraints. Second, the deterministic model is generalized into a stochastic model considering uncertainties in the renewable generation and power loads. Several statistical models are developed to depict charging curves of battery electric vehicles with and without the demand response, so as to model an electric vehicle charging stations. Further, a Gaussian distribution model and K-means are adopted to estimate prediction errors of renewable energy sources and electric vehicle charging stations by constructing classical stochastic scenarios. Finally, discussion and analysis are performed on a modified IEEE 33-bus distribution network. The simulation results show that the proposed stochastic model can provide optimal day-ahead scheduling strategies and probability distributions of voltages and power losses to account for the uncertainties.","PeriodicalId":403002,"journal":{"name":"2023 8th Asia Conference on Power and Electrical Engineering (ACPEE)","volume":"141 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123276909","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}

Micro Gas Turbine Power Generation System based on Superconducting Magnetic Energy Storage to Cope with Pulsed Power Load 基于超导磁储能的微型燃气轮机发电系统应对脉冲功率负荷

In other words, it can not respond quickly to changes in load. When the load impact is extremely strong, it may lead to the collapse of the system. This makes it an important issue to make the MGT power generation system quickly balance the instantaneous power difference under the pulsed power load condition. In this paper, to cope with this possible situation, superconducting magnetic energy storage(SMES) with fast response is considered as the power-fast compensation method. When the pulsed power load is detected, the SMES is given priority to provide power for it, and to ensure the smoothness of the superconducting output power, the instantaneous power output of the SMES is considered as its power exponential change law with time. The simulation results show that when the MGT generates power independently, it shows strong oscillation characteristics in response to the shock load. And may even cause the DC side voltage to cross the limit because the power cannot be regulated in time, so that the system is shut down. In contrast, the SMES as the power generation compensation of the MGT power generation system shows excellent shock load resistance when dealing with pulsed power load.","PeriodicalId":403002,"journal":{"name":"2023 8th Asia Conference on Power and Electrical Engineering (ACPEE)","volume":"81 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121672025","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}

PV power prediction technology provides a reference for the development of dispatching plan, but it is difficult to realize the stable access of fluctuating PV power only by power prediction and dispatching. In this paper, a source and reservoir cooperative control method considering the effect of wave smoothing and the economy of operation is proposed, and a mathematical model of hybrid energy storage is constructed. By fully mobilizing the regulation potential of the power supply side and the energy storage side, the operation mode of the PV panel is changed briefly when the power changes dramatically and the hybrid energy storage system (HESS) is mobilized to provide power compensation, which effectively reduces the fluctuation rate of the grid-connected PV power. Simulation results show that the proposed strategy is effective.","PeriodicalId":403002,"journal":{"name":"2023 8th Asia Conference on Power and Electrical Engineering (ACPEE)","volume":"21 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122102400","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}
