Coordinated Air Conditioning Resources Scheduling with High Photovoltaic Penetrations

Controllable air conditioning loads (ACLs) and distributed renewable energy sources have become one of the research focuses in recent decades. This paper aims to propose a new control strategy which can schedule the interruptible ACLs and increase the photovoltaic (PV) penetration rate in distribution network, with battery energy storage system (BESS) involved in the scheduling process. The control scheme is modelled and further transformed into a MILP (mixed integer linear programming) problem whose objective function is to minimise the system operation costs. In order to guarantee the thermal comfort of customers, an advanced two-parameter thermal model is applied to describe the indoor thermodynamic transition more accurately. The proposed scheme is tested on a five-node radial distribution network based on large-scale integrated commercial buildings. The simulation results demonstrate the efficiency of proposed control scheme.
