Scientific results:
The goal of the project is to create a modern laboratory for software and hardware modeling of electric networks and solving a number of problems of modern energy industry on its basis. The primary focus was placed on networks with high shares power electronics devices both on the consumer side and on the generation side. This includes solving problems of managing networks with high shares of renewable power sources.
The project includes three blocks:
Block 1. Developing representative models of components of power systems. This block includes the development of models of the main modern components, such as Solar and wind power stations (with various types of grid connection), storage systems, the main types of loads as well as aggregate load models. These models are further integrated into the RSCAD environment for their use in the RTDS system. Complete models with the resolution of electromagnetic degrees of freedom as well as with detailed modeling of devices of power electronics. Such models are aimed at detailed simulations and require major computational power. Simplified models only account for a part of degrees of freedom. They are required to be used in models of large energy systems, for which the use of complete models is impossible due to limitations of computational power.
Block 2. Developing methods for monitoring the state of networks and for identifying parameters of components of energy systems. Within this direction, we are developing a number of methods for the assessment of the states of networks, the limits of their stability, as well as methods of determining the parameters of systems from measurement data (for instance, from data of systems for monitoring of transient modes). One of the main objective is to develop identification methods relying on data of «background» measurements not related to large-scale transition processes. Also as part of this block we are developing a data collection and visualization system integrated with the RTDS software and hardware modeling system.
Block 3. Developing new methods for automated control and relay protection systems for modern electrical networks. Within this direction we are developing methods of network control under conditions of a large share of power electronics, in particular, methods of controlling renewable energy sources and storage systems. The use of the capabilities of modern power electronics devices (most often, inverters) allows to develop qualitatively new controlling inputs, such as: fast frequency tuning, stable control of generation and (or) consumption. On the other hand, the majority of classical principles of control and relay protection need to be revised.
Practical significance of research:
The results achieved in the project allow to increase the reliability of modern electrical networks, decrease operating costs, significantly decrease «price thresholds» for the implementations of modern systems (for instance, storage systems), simplify the procedure of integration of renewable power sources and increase the maximum allowable share of such sources.
