Demand response: For congestion management or for grid balancing?

The growing capacity of intermittent energy sources causes more frequent system imbalances as well as congestion. Demand flexibility is a valuable resource that can be used to resolve these. Unfortunately, flexibility can also contribute to congestion, particularly when used to balance the grid. Using flexibility to solve grid problems...

Decentralized Optimal Power Flow for Bipolar DC Grids: An algorithm for online optimization using grid measurements and droop control

The optimal power flow (OPF) problem is a classic and widely-studied topic in the field of power systems.Its purpose is to minimize the running costs of a power system by determining the optimal operating points,while respecting a set of physical constraints. While most power systems are currently controlled by a centralcoordinator, there is...

Quantifying the Contribution of distributed flexible loads to congestion management

The electrical network must have adequate capacity to avoid congestion for all but the highest load levels. The most common solution to manage this congestion is to gradually invest in new infrastructure. An alternative solution for congestion management is the use of flexible loads, or demand response. In order to determine the relative value...
