Sensor deployments on the grid are expected to increase geometrically in the immediate future, while the demand for clean energy generation and policy changes are driving the use of non-dispatchable power sources, such as solar and wind. New demands are being placed on the power infrastructure due to the introduction of plug-in vehicles. These trends reinforce the need for higher fidelity simulation of power grids, and higher frequency measurement of their state. Traditional grid simulation and monitoring tools cannot handle the increased amounts of sensor data or computation imposed by these trends. The use of high performance computing and networking technologies is of paramount importance for the future power grid, particularly for its stable operation in the presence of intermittent generation and increased demands placed on its infrastructure. The workshop intends to promote the use of high performance computing and networking for power grid applications.
