Many research institutions have made different progress in the research on inertia of new power systems. However, there is still a lack of consideration of system inertia characteristics in power system planning. Therefore, in order to suppress the large change of system frequency caused by active power disturbance in the receiver system under the high proportion of new energy access, this paper proposes an inertia support planning method to improve the receiver system under the variable proportion of new energy access from the perspective of power system planning. First, the meaning and composition of the inertia of the power system are expounded and the minimum inertia required for the frequency stability of the system is analyzed. Secondly, considering the potential contribution of diversified resources of “source-network-loadstorage” to the equivalent inertia of the system, inertia resources including traditional synchronous generator inertia, load inertia and virtual inertia are considered. The inertia support planning model of receiver system is proposed to solve the problem of low inertia support of receiver system under high proportion of new energy access. Finally, the GAMS (The General Algebraic Modeling System) modeling and simulation is used to verify the effectiveness and feasibility of the proposed method and model.","PeriodicalId":447871,"journal":{"name":"2022 5th International Conference on Power and Energy Applications (ICPEA)","volume":"31 6 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-11-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116413150","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 inverter limits the common mode voltage of the system to 2/3 times of the DC side voltage without increasing the system loss and control difficulty, so as to effectively suppress the system leakage current. At the same time, a model-free predictive current control method based on the ultra-local model is proposed. The gain and dynamic part of the ultra-local model of the inverter are updated online using the voltage and current information of the past two times, and then the predictive voltage vector of the next time is obtained. This method does not require the accurate model of the inverter and any system parameters. Finally, an experimental prototype with TMS320F28335 as the control chip is developed. The simulation and experimental results show that the proposed inverter and its control strategy can effectively suppress the leakage current of the photovoltaic grid connected system and improve the robustness of the system.","PeriodicalId":447871,"journal":{"name":"2022 5th International Conference on Power and Energy Applications (ICPEA)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-11-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125822571","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 the excess power is directly connected to the grid, it may increase the long-distance transmission loss and reduce the energy utilization rate. However, the amount of electricity available for allocation in the internal distribution network of a multi-microgrid system is often less than the user load demand. Based on this, this paper proposes a multi-time scale hierarchical coordinated control method for multi-microgrid partition autonomous energy cooperation community, including three levels. Firstly, the middle layer focuses on the supply and demand balance of each local microgrid subsystem and optimizes the charging and discharging of its energy storage equipment. Then, the distribution network (DNO) controller at the top layer obtains the supply and demand imbalance information of all subsystems, and optimizes the transaction power between the DNO and the AMG after comprehensive analysis. Finally, the underlying set controller makes the corresponding load interruption according to the optimization results of the upper and middle layers, and updates at a faster sampling rate.","PeriodicalId":447871,"journal":{"name":"2022 5th International Conference on Power and Energy Applications (ICPEA)","volume":"5 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-11-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125037135","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}
