A mixed integer programming approach for optimal power grid intentional islanding

Load-shedding Strategies for Preventing Cascading Failures in Power Grid

“…There is some work discussed in [34] for optimal islanding. Although these islands are optimal, it is usually not a scalable problem.…”

Optimal intentional islanding to enhance the robustness of power grid networks

“…Since the past few years, the problem of intentional islanding is being studied as an important approach for isolating failures in the power grid [20], [21], [23], [25], [27], [29], [31]. It has been proposed by some researchers as an appropriate control action to protect the system when large disturbances take place.…”

“…The authors of [29] and [30] present a mixed integer programming approach for optimal power grid islanding, both with the objective of minimizing load shedding only within the island. The authors of [29] also discuss connectivity constraints so that the nodes within each island are connected. As opposed to the techniques mentioned before, these two optimization techniques can form multiple islands at the same time.…”

“…The use of the DC model allows the optimization to easily converge for a few test cases in spite of its complexity. The DC model has been used in the recent works [29], [30] for islanding using MIP.…”

Doubly Balanced Connected Graph Partitioning

“…When the island is large enough compared to the initial network, it is more likely that it has enough capacity. This problem has been studied in the power systems community but almost all the algorithms provided in the literature are heuristic methods that have been shown to be effective only by simulations [8,[14][15][16].…”
