Centralized system of optimal power frequency control of electrical power system with renewable energy sources

One of the priorities of the energy power system (EPS) modernization is the creation and implementation of transitional regimes monitoring, which are used to improve information provision and quality of EPS regimes management. Current approaches to the control of electric power systems are based on the use of mathematical models, which are essential in performing optimal control. Obtained from the transitional regimes monitoring system (TRMS) data are used to identify the model of the electricity system that is adequate as relate to the frequency change and makes it possible to control the EPS transitional regime. The obtained EPS model can be improved on the basis of the known structure and composition of the EPS main equipment. Renewable energy sources (RES) peculiarities such as variability and unpredictability as well as connection to the distribution network make systemic regulation rather complicated. Relevance of the work is necessitated with the need to develop new approaches to the management of EPS with lots of RES. Using controlled renewable energy sources (RES) and controlling frequency improves regulation efficiency. The structure and algorithms of hierarchical system of centralized management that make it possible to control frequency using RES have been worked out
