Abstract

Abstract:

The smart grid does provide people with enormous benefits, however, but it possibly leads to serious security problems. The cyber attack on real-time pricing (RTP) is of great significance, but people pay less attention to. Focused on delay attack, a dynamic model for behavior of both consumers and suppliers in electrical power markets was established. Based on the model, a defensive pricing strategy using robust control theory and Lyapunov function was put forward. At last, the effectiveness of the proposed strategy was validated through a numerical simulation example.

Key words: smart grid, real-time pricing, delay attack, cyber-physical system
