220kV City Power Grid Maximum Loadability Determination with Static Security-constraints

Loadability of power systems with steady-state and dynamic security constraints

Estimating loadability of a generation and transmission system is of practical importance in power system operations and planning. This paper presents a new formulation for the problem using mathematical programming theory. Both steady-state and dynamic security are taken into account in the proposed formulation. The difference between the proposed formulation and existing ones is that dynamic ...

Interactions among Limits during Maximum Loadability and Transfer Capability Determination

The main idea of this paper is to illustrate the interaction between various kinds of power system operational limits and corrective actions. In particular, the paper focuses on the interplay between line flow limits and active generation redispatch as the corrective action. The proposed methodology handles a wide range of flow limits by explicit inclusion of line flow equations into the set of...

Predictive Smart Grid Control with Exact Aggregated Power Constraints

This chapter deals with hierarchical model predictive control (MPC) of smart grid systems. The design consists of a high-level MPC controller, a second level of so-called aggregators, which reduces the computational and communicationrelated load on the high-level control, and a lower level of autonomous consumers. The control system is tasked with balancing electric power production and consump...
