Investigating scalable computational tools and infrastructure to enable interoperable and secure control of large-scale power systems

The UK government has set an ambitious target in the proportion to be generated from renewable sources by 2020 in order to decarbonize the UK electricity. Based on these targets the Electricity Networks Strategy Group (ENSG), developed a "Gone-Green" scenario for the energy mix, which outlines the anticipated rise in generating capacity from wind. The challenge imposed in incorporating this volume of renewable energy is significant, introducing new technical and system balancing demands. In addition, significant changes will be required with regard to interoperable and scalable operational modeling and analysis procedures in order to secure such future transmission networks. Investigation, development and deployment of emerging industry standards such as the Common Information Model (CIM) on high performance computational platforms to fully enable interoperable power system data exchange both internally and externally to electrical power network operators, such as National Grid is under process. The new systems, whilst adding increased levels of monitoring and possibly control will provide a huge challenge operationally. In order to accommodate the network changes, an increased amount of flexibility will be required from the system in addition to significant improvements in operational control procedures. Key to achieving this will be coordination between all of the individual control systems facilitated by an increase in the availability of real-time data on the state of the power system. To that effect, WAMS in the form of a resilient network of PMU\´s is required to improve situational awareness for network operators. In this paper the emerging industry development and future planning has been presented to understand the upcoming challenges on transmission network as well as in the distribution systems.
