报告摘要：
1.The Volterra integral-functional series is the classic approach for nonlinear black box dynamical systems modeling. It is widely employed in many domains including radiophysics, aerodynamics, electronic and electrical engineering and many other. Identifying the time-varying functional parameters, also known as Volterra kernels, poses a difficulty due to the curse of dimensionality. This refers to the exponential growth in the number of model parameters as the complexity of the input-output response increases. The least squares method (LSM) is widely acknowledged as the standard approach for tackling the issue of identifying parameters. Unfortunately, the LSM suffers with many drawbacks such as the sensitivity to outliers causing biased estimation, multicollinearity, overfitting and inefficiency with large datasets.This paper presents alternative approach based on direct estimation of the Volterra kernels using the collocation method. Two model examples are studied.It is found that the collocation method presents a promising alternative for optimization, surpassing the traditional least squares method when it comes to the Volterra kernels identification including the case when input and output signals suffer from considerable measurement errors.
2.A key role in the theory of fiber spinning is played by hydrodynamic models described by nonlinear boundary layer problems. The report examines such boundary value problems using modern methods of functional analysis, hydrodynamics and computational mathematics. An analytical method for constructing solutions in one-dimensional stationary models with boundary conditions has been developed. A numerical method is proposed whose relative errors in determining the characteristics of the heat flow for a flat plate do not depend on the Reynolds number. Theorems on the existence of solutions to boundary value problems arising in physical and technical models of polymers are proven using the Cauchy-Kovalevskaya theorem and the Schauder fixed point principle. Using general existence theorems for solutions of nonlinear equations with a vector parameter, the existence of solutions to a boundary-value problem from boundary layer theory on an unbounded half-interval is proven. The report is intended for specialists in the field of industrial mathematics, its applications in chemical technology, in the theory of materials, as well as scientists and engineers interested in nonlinear boundary value problems.
3.The energy communities based on the integration of microgrids make it possible to gain economic, environmental, technical, and social benefits. The paper aims to propose a unified multi-criteria approach covering both the planning stage and the stage of managing the energy community, in the context of various interests of its participants. Planning stage should take into account the long-term goals of the community and possible changes in external conditions. Therefore, we suggest an approach relying on the multi-attribute value theory considering the uncertainty of decision makers' preferences. Interval estimators used to express preferences enable a choice of community configuration with robust performance under changing conditions within some limits. In the operation stage, the new multi-criteria model of an intelligent "energy community operator" is proposed. It is based on bi-level programming and reinforcement learning, implementing the structure of a fair local market for sustainable development of the community. To optimize the operation of individual microgrids within the community, the multi-objective Monte-Carlo Tree Search (MCTS) algorithm is used, which helps to improve the convergence in the Stackelberg game. The multi-criteria version of the MCTS algorithm allows implementing an adaptive local automation model to solve a multi-objective lower-level problem: minimize operating costs, risk of power shortage, and CO2 emissions; smooth load peaks, and optimize power exchange between microgrids. At the top level, a management strategy that will be beneficial to all members of the community is chosen to guarantee their long-term aggregation. The effectiveness of the proposed approach is demonstrated by the example of an energy community created for three remote villages located on the coast of the Baikal lake. The natural and climatic conditions of the area allow the efficient use of wind, solar, and biomass resources. Building the community involves the consideration of three scenarios, in which priority is given to economic efficiency, environmental efficiency, or balanced development。
4.This lecture provides soft introduction to the conteporary theory of linear and nonlinear Volterra (evolutionary) integral equations of the first kind: essential tool for hereditary dynamic systems modeling. In our approach we focus on the case of piecewise continuous (jump) Volterra kernels. The existence and uniquness theory of the local global solutions will be presented. The robust numerical methods will discussed for both cases: integer and fractional order. The application of the costructed theory to energy balance and strorage control will be discussed.
5.The datasets representing the different seasons including the photovoltaic data and meteorological data were employed. The neural networks fusion method is proposed using LSTM, RNN and Dense archetectures. Three kinds of neural networks to train and predict each season , the final prediction model is formed by weighting are combined , and the weights are optimized using the Nelder-Mead method. The model is tested by randomly selecting data from other years and adding artificial disturbances. The test results prove that the weighted model has strong stability and generalization ability, and the prediction error is smaller than that of the single model.
