Abstract. This paper demonstrates the application of algorithms for dynamic calculation model of electric power system optimization in the PC RUSTab to automate verification process, regularly carried out in dispatch centers for models of both regional and united power systems. The algorithms under consideration differ in their a priori characteristics – complexity of calculations, speed of convergence, method’s resistance to errors in calculations, sensitivity of method to algorithm parameters values, as well as the use of derivatives in objective function calculation. The paper provides theoretical calculations on optimization algorithms functioning that are compared with each other, shows the result of their application for verifying a simple electric power system test model and a large scale model of real electric power system, and analyzes the trajectory of changes in the model parameters during optimization process. The result of work is the values of optimized parameters obtained using the algorithms, as well as the graph of transient processes when these values are substituted into the model.
Keywords: optimization algorithm, target function, number of iterations, Levenberg-Markwardt algorithm, Bayes algorithm, genetic algorithm, optimal value, local minimum.
Formation of Requirements for The Operation of Grid-Forming Power Converters the Power System
Zhou H., Nаsyrov R.R., Burmeyster M.V., Guo L., Bulatov R.V. (NRU «MPEI», Moscow)
Abstract. The increasing integration of renewable energy sources reduces the equivalent inertia of power systems and deteriorates their transient stability conditions due to the extensive use of power electronic converters. Autonomous (gridforming) converters and virtual inertia systems are regarded as key technologies to address this challenge. This study presents a comparative analysis of regulatory and technical requirements for grid-forming converters in the documents of the United Kingdom, the United States, Australia, China, and Finland. The analysis covers requirements related to frequency and voltage control, inertial response, and other performance indicators. Both common principles and national specificities are identified, forming the basis for further standardization and wider deployment of this technology. Based on the analysis of foreign technical regulations, recommendations are provided for the development of a Russian standard regulating the operation of grid-forming converters.
Keywords: frequency control, grid-forming converters, gridfollowing converters, virtual inertia systems, integration of RES integration, technical specifications.

Semiconductive Layer Over the Cable Sheath. Issues and Solutions
Dmitriev M.V., (FGAOU DPO «PEIPK», Saint-Petersburg)
Abstract. Modern cross-linked polyethylene insulated cables play a key role in the country’s energy system and are widely used in both MV (6-35 kV) and HV (110-500 kV) networks. One of the specific features of HV cables is their sheath that sometimes is covered with a semiconductive layer that facilitates detection of its damage. It turned out that in certain situations this layer might not be helpful, but harmful. Due to the significant cost of such cables, the author considers it useful to share the information about such cases provided by the owners of the lines with the readers and to suggest possible remedies.
Keywords: cable line, single-core cable, cross-linked polyethylene (XLPE), cable outer sheath, semiconductive layer over the cable sheath, sheath testing, sheath damage.
