The paper describes the approaches to ensuring the supply reliability of power supply from the power system, presents approaches to the normalization of reliability indicators. The approach to continuous planning and correction of the developing solutions is outlined. The decision maker should be able quickly evaluate the optimality of decisions on changes in the structure of traffic flows in the system, the operational characteristics of facilities, the use of reserves, and the effectiveness of management under various hypotheses regarding the dynamics of supply and demand. In modern conditions, the time reserves for making decisions are limited, and the amount of available information and requirements for detailing decisions have increased significantly, which tightens the requirements for automation and computerization of planning and operational management. One of the approaches to the development of a control system for power system is the use of logical simulation of a power system implemented on the principles of hierarchical modelling.

The main advantage of logical simulation is the ability to solve complex problems of energy system management, which are often impossible to solve within the framework of other approaches: ensuring reliable power supply of consumers; optimal use of all available system reserves; minimizing the consequences of the implementation of abnormal and emergency situations caused by natural, man-made, social and political risks; compensation for seasonal irregular power consumption; ensuring the stability of the power system during periods of cold snaps and abnormally cold winters.

Improvement of existing and development of new models for managing the reliability of power systems will allow creating effective tools of intellectual and data computing support for decision making in managing the development and operation of power systems.
