Abstract
In electric power systems, decentralised computer systems have been proposed for voltage and power static estimation. They reduce th eamount of centralised information on the supervisor computer. A system of multi-area computer hierarchy particularly adapted to handle the problem of real-time intervention on electric power systems is presented. The overall optimization problem is formulated according to Lagrange, introducing the interaction constraints among the areas in the objective function. Concerning the active power subproblem, the economic dispatching for a given configuration of voltages and loads is examined. The resulting problem has a decomposable structure which can be solved by a two-level iterative computation, that is by goal coordination or interaction balance method.Beagle algorithm is used for local constrained quadratic optimizations for a given value of lagrange multiplier. The supervisor computer iteratively up-dates the lagrange multiplier to guarantee the interaction balance, using gradient like algorithms.The conditions where this method is applicable are recalled and particularized for the economic dispatching problem.

The swing generator model
The consequences of electric power outages dictate the importance of conducting power system studies. These studies will most likely be based upon models that combine representations of the various components (e.g., generators, loads, and network) in the power system.This paper considers a classical flux-decay model to which the proposed reduced model will be compared. Both models incorporate the swing equation and differ primarily in the voltage control and excitation dynamics.the swing equation captures the mechanical dynamics of the generator through rotor angle delta and generator speed omega. The proposed reduced model replaces the voltage and excitation dynamics of the flux-decay model with a single state model that captures the basic characteristics of the flux-decay model.The voltage dynamics, effects of imposing excitation limits, and steady-state behavior are taken into account here through a simple model.Combining the exciter with the swing equation yields a new generator model with behaviors chosen to be similar to the flux-decay model.It is called the called the saturated swing generator model. the reactive power limitation of the generator can be a cause of voltage instabilities. Similarly bifurcation diagrams of the saturated swing model can be created.When the saturated swing generator model is considered (with varying limiting values) it is shown that as the load is increased the bus voltage decreases. This Similar results occur when the saturated swing model is considered for both the lightly and heavily loaded system.Another important benchmark is to see how the saturated swing generator responds to a step increase in a reference voltage. for details, read this report: swing generator model.pdf (Size: 120.53 KB / Downloads: 109) |
