DYNAMIC STABILITY ASSESSMENT AND OPTIMIZATION FOR MIXED ENERGY POWER GRID OPERATIONS

System and method ensure stability of power transmission system or power grid with mixed generation sources of renewable and non-renewable types while providing a best combination of stability services that minimizes both cost of generation and guaranteed reliability. An energy market management (EMM) module derives an energy market dispatch for a mix of generation sources including renewable and conventional types based on a steady state optimization of supplier cost and a power demand forecast. Dynamic Security Assessment (DSA) module performs a dynamic contingency assessment of stability for the power transmission system based on the energy market dispatch and sends feedback to the EMM module with results of the dynamic assessment of stability. EMM module clears the energy market dispatch on a condition that feedback indicates a stable dynamic assessment. For unstable assessment, data driven, model-based and/or rule-based algorithms provide recommendations on how EMM module can find stable market solutions.
