AI Technical Summary

Technical Problem

Current methods for balancing electric power systems face challenges due to the volatility and uncertainty of renewable energy sources, non-convex market participant and transmission constraints, and the complexity of market clearing mechanisms, which are inefficient and often result in overproduction and difficulty in directing energy flows to demand.

Method used

The method employs a robust multilevel optimization approach using bi-level formulations, semidefinite programming relaxation, and convexification techniques to model power systems dynamics, allowing for efficient market clearing near real-time and robustness against uncertainty, incorporating time-varying processes and transmission constraints.

Benefits of technology

This approach provides global convergence guarantees and efficient resource utilization, stabilizing the energy network by directing energy flows to demand, reducing financial costs, and improving the stability of the power grid.

Abstract

Present invention relates to a method of balancing electric power systems using multilevel optimization, wherein the method employs steps which shall primarily result in channeling power flows by clearing electricity markets, i.e., matching bids, close to real time. The method comprises following step of using a robust bi-level formulation, along with using a semídefinite-programming relaxation of the polynomial optimization problem to capture transmission constraints at the transmission-system operator (market operator) level and using extended formulation of the market-participant level to optimize run-time of the operation to effectively convexify the market-participant level.
