High penetration levels of distributed generation may result in reversal of power flow in modern distribution grids. We have shown that reversed power flow may result in appearance of new previously unobserved operating equilibria.
The resulting solutions are generally low-voltage and undesirable for normal operation. However, the system may get trapped in those conditions during the post-fault recovery. We have proposed new algorithms for identification of all the solutions, as well as special emergency control actions that can help maintain stability and enable adoption of high levels of clean renewable energy.
