SOSPO - Secure Operation of Sustainable Power Systems
Focus is on how control of the power system, at transmission level, needs to be changed to meet the needs of stable and uninterrupted power, despite the fluctuating energy sources in the grid of the future. The project will address the future power system at the transmission level and develop methods for real-time assessment when unsafe operation is approaching and it will make control countermeasures as needed.
Future visions for a society with minimal dependency of fossil fuels require a large share of electric power production from sustainable energy sources. The focus of previous and present research is on how consumers can be controlled given the fluctuations in green power production. SOSPO, by contrast, focus is on how control of the power system, at transmission level, needs to be changed to meet the needs of stable and uninterrupted power, despite the fluctuating energy sources in the grid of the future. Technologies that today control the system and ensure a stable and reliable supply will be inadequate. Geographic and dynamic changes in production cause alterations as dynamic as nature. Existing controls are not built to this and the future power system will be vulnerable. Secure operation, needed and expected by society, will require novel concepts for supervision and control at the transmission level.
The SOSPO project will address the future power system at the transmission level. It will develop methods for real-time assessment when unsafe operation is approaching and it will make control countermeasures as needed. Novel advances (patent pending by DTU) in wide-area stability and security assessment will be employed [1, 2]. Stability and security assessment (SSA) information will determine control actions according to the severity of the condition. Novel mathematical control theory (L1 design) [3, 4] will offer entirely new solutions in both linear and nonlinear regimes. Emphasis will be put on recovery in emergency operating conditions. SOSPO will be essential for the future intelligent power system [5, 6] and results will be validated and demonstrated at PowerLabDK, a world-class experimental facility at DTU.
The consortium consists of leading research groups and companies, who co-finance SOSPO.
The objective of the SOSPO project was to carry out research and development of methods capable of assessing system stability and security in real-time, and in methods for intelligent wide-area control that can reestablish stable and secure operation when critical operating conditions have been identified.
The project results included several innovative methods for real-time assessment and control that can contribute to secure operation of future power systems. The SOSPO results have resulted in a startup of a new project, which focuses of further development of the SOSPO methods towards implementation and demonstration a real-life power system.
