Technology Description:

Bigwood Systems is developing a comprehensive Optimal Power Flow (OPF) modelling engine that will enhance the energy efficiency, stability, and cost effectiveness of the national electric grid. Like water flowing down a hill, electricity takes the path of least resistance which depends on the grid network topology and on grid controls. However, in a complicated networked environment, this can easily lead to costly congestion or shortages in certain areas of the electric grid. Grid operators use imperfect solutions like approximations, professional judgments, or conservative estimates to try to ensure reliability while minimizing costs. Bigwood Systems’ approach will combine four separate analytical technologies to develop an OPF modeling engine that could markedly improve management of the grid. As part of this project, Bigwood Systems will demonstrate the practical applications of this tool in partnership with the California Independent System Operator (CAISO).
