Dynamic Stochastic Optimal Power Flow Control for Power Systems with Intermittent Renewable Energy Generation

Market Overview:

Renewable energy such as wind, photovoltaic, and solar thermal generation require control of power systems that account for high short-term variability and uncertainty with these intermittent energy sources.  Power system security needs to be ensured dynamically as the system operating condition continuously changes.  This technology features a dynamic stochastic optimal power flow (DSOPF) control system for performing multi-objective optimal control capability in complex electrical power systems.  The DSOPF system and method replaces the traditional adaptive critic designs (ACDs) and secondary voltage control, and provides a coordinated AC power flow control solution to the smart grid operation in an environment with high short-term uncertainty and variability.  The DSOPF system and method is used to provide nonlinear optimal control, where the control objective is explicitly formulated to incorporate power system economy, stability and security considerations. The system and method dynamically drives a power system to its optimal operating point by continuously adjusting the steady-state set points sent by a traditional optimal power flow algorithm.
