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

Market Overview:

This technology is aimed at better integration and control of renewable power sources into conventional power utilities. With growing concerns over environmental impact of coal and gas power, there is an ever-increasing rise of wind, solar, and geothermal energy generation being brought online. It is expected that by 2023 that about 12% of the total global energy supply will be from renewable energy sources. By 2025 this market is expected to be valued at $1.49 trillion. This technology would help facilitate the increase of these new sources by controlling their unpredictability and managing the high short-term variability associated with intermittent energy sources. 


Application                                                                           Stage of Development

Renewable Energy/Power Systems Control                          Optimized technology ready for licensing




• Provides regulation and optimization for both active and reactive power

• Enables addition of renewable energy sources without need for upgrading line capacities

• Accounts for high short-term variability and uncertainty associated with intermittent energy sources 


Technical Summary

This technology integrates aspects such as power system economy, stability and security into the formulation of the DSOPF methodology to help achieve the goal of non-linear optimal control. This proposed DSOPF system can replace other methods such as adaptive critic designs and secondary voltage control to help ensure that a coordinated alternating current power flow is created. Therefore, highly variable energy systems, such as those associated with renewable energy sources, can be continuously maintained at optimal operating status through adjustment of set points within established algorithms.
