Research Topics

  • Optimal planning and operation of transmission and distribution networks with a high share of RES. In this part, the activities are related to:
    • Development of methods for optimal extension planning of transmission/distribution networks with a high share of RES,
    • Development of methods for the optimal operational management of power networks to increase grid hosting capacity under the current network state,
    • Analysis of the different sources of flexibility to create conditions for the energy transition of the classic power system to RES-based systems.

 

  • Optimal microgrid management. In this part, the activities include:
    • Application of model-predictive control methods for optimization of microgrid operation and creation of conditions for participation in the ancillary services market,
    • Application of machine learning methods to develop generic approaches for optimal microgrid management.

 

  • Application of machine learning methods and deep neural networks in power equipment diagnostics and relevant power system parameter forecasting. Activities in this section include:
    • Development of methods for forecasting important market/power system parameters such as day-ahead / intra-day load forecasting, forecasting the production of wind farms / PV power plants, forecasting hydrological conditions at the level of individual basins, etc.
    • Development of methods based on machine learning and Bayesian statistics for forecasting and classification of equipment condition in power facilities.
    • Development of methods based on machine learning for the analysis of transient stability and power system fault classification.

Description of laboratory and equipment

For the realization of the above objectives and activities, the existing laboratories at the Department of Power Engineering(laboratory A246 and B309) will be used. These laboratories will be equipped with computer and laboratory equipment (protection relays of different generations, measuring equipment,…) and specialized software packages for the analysis and simulation of power systems (MATLAB, PowerFactory, GridLAB, OpenDSS, PowerCAD, WinDIS, EMTP, Anaconda, etc. .). In the next five-year period, a significant upgrade of laboratory equipment is planned, which would be financed through other financial sources, and the procurement of the same will complement the existing laboratory computer and software resources. Through the VIF financing program, small value equipment will be procured: measuring equipment of small value, laboratory consumables, maintenance of licenses for various software packages,…

Application of advanced optimization and machine learning methods for optimal planning and control of power systems with a high share of RES (ADVANCE - RES)

Project research activities

Trends in the development of electric power systems indicate the fact that the period of the next 5 years will mark the period of generating units based on RES. To ensure safe and reliable operation of the power system in such operating conditions, significant investments in capital equipment at the power system level, or the development of advanced methods of power management and control that will avoid or reduce these costs are necessary. Given these trends, the focus of the research group will be on the development of advanced methods of optimization and machine learning and their application in the planning and management of power plants with a high share of RES. For this purpose, the goals of the research group will be directed in several directions:

  • Optimal planning and operation of transmission and distribution networks with a high share of RES. In this part, the activities are related to:
    • Development of methods for optimal extension planning of transmission/distribution networks with a high share of RES,
    • Development of methods for the optimal operational management of power networks to increase grid hosting capacity under the current network state,
    • Analysis of the different sources of flexibility to create conditions for the energy transition of the classic power system to RES-based systems.

 

  • Optimal microgrid management. In this part, the activities include:
    • Application of model-predictive control methods for optimization of microgrid operation and creation of conditions for participation in the ancillary services market,
    • Application of machine learning methods to develop generic approaches for optimal microgrid management.

 

  • Application of machine learning methods and deep neural networks in power equipment diagnostics and relevant power system parameter forecasting. Activities in this section include:
    • Development of methods for forecasting important market/power system parameters such as day-ahead / intra-day load forecasting, forecasting the production of wind farms / PV power plants, forecasting hydrological conditions at the level of individual basins, etc.
    • Development of methods based on machine learning and Bayesian statistics for forecasting and classification of equipment condition in power facilities.
    • Development of methods based on machine learning for the analysis of transient stability and power system fault classification.
    • Development of machine learning-based methods for the classification of power system faults.

 

  • Formation of laboratory for microgrid and real-time power system simulation:
    • Procurement of equipment for microgrid development through other founding sources The equipment will be used to test the developed algorithms and methods and implement advanced microgrid management strategies;
    • Procurement of equipment for real-time simulation of power system operation, which would examine the possibility of implementing the developed algorithms and analyze the effects of their application.
