Evaluation of cooperative demand control system on micro grid

Abstract

KNIVES (Keio University Network oriented Intelligent and Versatile Energy saving System) is an IT based supply and demand side management system that supports distributed and cooperative power control. In this study, KNIVES is constructed on a real experimental facility of microgrid. The facility includes some distributed power generator and controllable/uncontrollable loads. It is also connected with general power grid. Therefore, it can introduce the electric power from the power grid when the power supply is insufficient. An experiment of demand control was achieved in this facility and the affectivity of KNIVES was confirmed. In this experiment, error ratio of demand balancing with distributed and cooperative demand controls were evaluated and compared with that without the demand control.

Demand-side energy storage system management in smart grid

“…By substituting (9) into (8), the tracking error dynamics can be further expressed as e(t + 1) = (A(a) + B((3)K)e(t) + llw(t) (10) where llw(t) = w(a, t) -B((3)B(!3)t w(a, t).…”

“…In [3], Nguyen et al considered an approach that minimizes the peak-to-average ratio in a distributed energy storage sys tem, and a pricing model was investigated. In contrast to a noncooperative design, a cooperative DSM system was proposed in [10] to improve the energy utilization efficiency. Cooperative smart grid networks were also considered in [11] to reduce average power losses over distribution power lines.…”
