The coordinated control of thermostatically controlled loads and energy storage considering the lock-out effect

In this paper, a coordinated control model based on empirical mode decomposition (EMD) is proposed for making full use of the load-flexibility from thermostatically controlled loads (TCLs). Based on the analysis of the impact of compressor-lock-out effect on the load-flexibility of TCLs, the coordinated control model is established to instruct TCLs and the energy storage (ES) to response to the low frequency and high frequency part of the control requirements respectively. The contrastive results illustrate that the proposed method can make full use of the flexibility potential of TCLs and enhance the performance of the ancillary service.
