Program on “Intelligent Networks”
The research presented in this work has been performed within the framework of the ’Intelligent Power Systems’ project. The project is part of the IOP-EMVT program (Innovation Oriented research Program - Electro-Magnetic Power Technology), financially supported by SenterNovem, an agency of the Dutch Ministry of Economical Affairs. The ’Intelligent Power Systems’ project is initiated by the Electrical Power Systems and Electrical Power Electronics Groups of the Delft University of Technology and the Electrical Energy Systems and Control Systems Groups of the Eindhoven University of Technology.
In total 10 Ph.D. students are involved and work closely together.
The project consists of four parts.
The first part, inherently stable transmission system, investigates the influence of uncontrolled decentralized generation on stability and dynamic behavior of the transmission network. As a consequence of the transition in the generation, less centralized plants will be connected to the transmission network as more generation takes place in the distribution networks, whereas the remainder is possibly generated further away in neighbouring systems. Solutions investigated include the control of centralized and decentralized power, the application of power electronic interfaces and monitoring of the system stability.
The second part, manageable distribution networks, focuses on the distribution network, which becomes ’active’. Technologies and strategies have to be developed that can operate the distribution network in different modes and support the operation and robustness of the network. The project investigates how the power electronic interfaces of decentralized generators or between network parts can be used to support the grid. Also the stability of the distribution network and the effect of the stochastic behavior of decentralized generators on the voltage level are investigated.
In the third part, self-controlling autonomous networks, autonomous networks are considered. When the amount of power generated in a part of the distribution network is sufficient to supply a local demand, the network can be operated autonomously but as a matter of fact remains connected to the rest of the grid for security reasons. The project investigates the control functions needed to operate the autonomous networks in an optimal and secure way. The interaction between the grid and the connected appliances has a large influence on the power quality.
The fourth part, optimal power quality, of the project analyzes all aspects of power quality. The goal is to provide elements for the discussion between polluter and grid operator who has to take measures to comply with the standards and grid codes. The Power Quality test lab is an integral part of the project.
