Power to the grid

Electrical power

Wind: an invisible force, but a powerful one that we are using a lot to our advantage. From flying kites, hot air balloons and planes, to enormous wind power plants for renewable energy. We can capture the power from the wind, we just don’t know exactly when. Dealing with the unpredictability of natural energy sources and its impact on the operation and planning of electrical power system  is what Jose Rueda Torres’s research is all about.

“Accurate forecasting of weather is something we have been improving over many years, but it is still a challenging task for science. Predictability is what we ideally need to meet  the growing demand of power supply from renewable energy sources, because it affects significantly the way we operate and plan electrical power systems. While we can have a certain degree of confidence when forecasting feasible power generation from renewables in the short-term (e.g. a few minutes to hours ahead), it is almost unavoidable to face high uncertainty when planning the operation for the next day, weeks, and months. Grid management involves several interrelated tasks across different time horizons (e.g. real-time operation, asset management, and grid development), which are highly affected by uncertainties introduced by renewables .

The current practice for power system operation and control is still conservative, which is mainly due to the relatively high predictability of conventional energy sources and the fact that power production should follow demand variations. Such approach will not be feasible in future systems with high volume of renewables and demand side response. This demands significant research effort to develop better policies and strategies for optimal and efficient grid management, including control and protection tasks.”

By 2030 at least 30 % of the power supply in Europe will have to come from renewables.

“My research is related to stability (the ability of the system to survive disturbances) and the development of intelligent control schemes. To ensure reliability and stability, power grids should successfully react to changing operating conditions and different types of disturbances, ranging from  planned outages  (e.g. due to maintenance) to unexpected events such as lightning. My fields of expertise are electrical power engineering and computational intelligences. The two combined are helping me to develop software based models of devices and controllers involved in renewable energy generation and coordinated grid operation. These models are essential to understand the dramatic change of power system performance due to increasing penetration of renewables. Intelligent control schemes can then be developed to mitigate instability risks.

The Migrate H2020 project (Massive Integration of Power Electrical Devices in Transmission Systems) is part of my current research activities. This is a multidisciplinary consortium with different lines of research about power grids. There is a lot of variety in data output (e.g. forecasted scenarios of grid development, time data series of power system variables, grid models, new technical requirements) and research tools (e.g. software based modelling and simulation, real-time digital simulation, hardware-in-the-loop tests). Moreover, part of the data is public, part is restricted to the consortium, and other developments will be strictly confidential. To organise all this is complex.

To organise the wide variety in data output is complex.

Together with the TU Delft Library we have set up a Data Management plan. We have set up templates and processes so that each research team deals with data the same way and we preserve our data in the 4TU.ResearchData  repository <link>. This way we  ensure that our data can be used in future, so that other researchers do not have to start from scratch and, equally importantly,  other researchers can corroborate our output. This is an important step. It makes our research more accessible and it shows the quality of research from our university.”
