The results showed that the inhibitory effect of ND on SiO2 agglomeration and its excellent intrinsic thermal conductivity and hardness successfully increased the $mathrm{T}_{mathrm{g}}$, thermal conductivity and bending strength of SiO2/epoxy composites by 9.94%, 5.59% and 9.94%, respectively, when the addition of ND was 6wt%.

The flexible DC transmission system can transmit power to the islanded power grids and improves the frequency stability of islanded grids by adding frequency control, which can actively participate in the dynamic process of frequency quality improvement. However, the frequency instability of islanded grids is easy to occur, and the typical frequency controls (such as droop, inertia and PD control) cannot compensate the power deficiency quickly and sufficiently. Considering the limitation of conventional strategies, the rapid power compensation (RPC) based frequency control strategy was proposed in this paper, which quantifies the transmitted power between the inverter and the islanded grid to determine the maximum power that can be generated by the inverter. When the disturbance of the islanded grid exceeds the specified threshold, the maximum power is directly used to fully use the capacity of the inverter and fill the power gap of the islanded grid to the maximum extent, and hence reduce frequency deviation and frequency change rate quickly. Besides, the simulation results also show that the RPC control is more suitable for low inertia systems, because of its remarkable effect under large disturbances.","PeriodicalId":447871,"journal":{"name":"2022 5th International Conference on Power and Energy Applications (ICPEA)","volume":"111 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":"116545512","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 energy storage system with strong regulation ability provides a solution. Reasonable planning of energy storage system is the key point. Therefore, aiming at the problem of renewable energy consumption in the new power system, this paper proposes an energy storage location and capacity planning based on distribution network partition and ResNet DNN. Firstly, the mathematical model is established according to the optimization objective of the energy storage system; Secondly, according to the output and consumption of nodes, the Lssvm is used to classify the data of load and renewable energy output, so as to partition the distribution network and determine the distribution area of the energy storage system; Finally, a deep neural network is established in each region and a residual block is introduced to determine the location and capacity of energy storage with the objective of the best consumptive ability. It decomposes the large-scale energy storage optimization problem into several sub problems, so as to meet the configuration requirements of large-scale energy storage system under the high proportion of renewable energy access. We use the typical monthly real data set in the standard IEEE 33 node for experimental analysis. Under different energy storage configurations, the proposed method can effectively promote the accommodation of renewable energy generation.","PeriodicalId":447871,"journal":{"name":"2022 5th International Conference on Power and Energy Applications (ICPEA)","volume":"33 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":"116575786","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 probability analysis model of battery failure of a power battery unit is established according to the normal working range of power battery parameters. Through the real-time monitoring of the working parameters (T, V, I) of the battery unit, calculate the probability value of each parameter that may trigger the corresponding fault. Based on the Analytic Hierarchy Process (AHP) method, calculate the weight of each parameter on the safety of the power battery. In the electrical safety analysis, the temperature weight is 0.65, the current weight is 0.23, and the voltage weight is 0.12. The calculated weights are assigned to the probability values calculated for each parameter to calculate the probability of battery failure, which also indicates the degree of danger in the state of the battery. This method can be used to determine whether a fault has occurred or is about to occur by extrapolating the fault rate from the real-time data of the power battery unit, which has a positive effect on the effective prevention of safety accidents caused by power batteries.","PeriodicalId":447871,"journal":{"name":"2022 5th International Conference on Power and Energy Applications (ICPEA)","volume":"43 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":"127325133","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 convection which happens in metal foam is added into the heat transfer. Bernardi model and local thermal equilibrium (LTE) model are employed to describe the heat generation of battery and the thermal transport in metal foam. The effect of channel fill ratio, porosity, inlet velocity, power consumption and the arrangement of exports are numerically analyzed. Decreasing the channel fill ratio and increasing the porosity will reduce the maximum average temperature and increase the temperature difference. The 3.58% decline ratio of the average temperature in the mode with channel fill ratio of 0.2 happens than that with channel fill ratio of 0.6. The 31.81% decline ratio of the maximum average temperature difference in the mode with channel fill ratio of 0.6 happens than that with channel fill ratio of 0.1. The channel fill ratio and the porosity influence the heat to be transported in the convection with air flow regularly.
