Optimal Value Determining Method of Parameters Compensating Devices of Bulk Electric Networks

The given method of optimizing the modes of main electric networks allows obtaining a universal approach for solving such tasks as minimizing the total losses of active power and compensating excess flows of reactive power. The methodology for selecting the parameters of compensating devices of controlled ultra-high voltage power transmissions with intermediate systems to ensure the balance of reactive power has been substantiated. An analytical solution to the problem of selecting the parameters of the compensating ultra-high voltage power transmission line with one intermediate system was obtained. An approach to solving the problem of optimization of the main electrical network is presented, taking into account the provision of reactive power balance. The objective function and its optimization criteria are described. The method of optimizing the mode of the electrical network according to voltage and reactive power was developed with an assessment of the effectiveness of the use of controlled compensating compensation devices, and the possibility of applying this approach was revealed. Recommendations are given on the use of reactive power compensators to improve the reliability and quality of power supply. The technique has been developed for evaluating the efficiency of controlled nodes based on optimizing the mode of electrical networks containing such nodes. In the work, two problems are solved when choosing installation sites and values of parameters of compensating devices: balancing reactive power and optimizing the operating modes of the main electrical network according to the criterion of minimum active power losses. The most efficient hardware based on static devices of the FACTS technological platform is proposed.
