Active Balancing Control Method for Thermostatically Controlled Loads Based on Energy Block Allocation Mechanism
Thermostatically controlled loads are important resource for regulating supply and demand balance in distribution networks.Efficient and feasible load control strategies enable distribution networks to achieve ideal supply and demand balance.The uncertainty of distributed photovoltaic output and the randomness of load starting and stopping behaviors can easily cause fluctuations in distribution network voltage and load.Therefore,this paper proposes an active supply and demand balance control method for thermostatically controlled loads based on energy block allocation mechanism to stabilize the load curve.A parsimonious algorithm is employed to optimize the sequence in which equipment utilizes energy blocks,ensuring that the load adjustment progressively converges towards the target while mitigating peak and valley fluctuations arising from simultaneous start-and-stop actions of multiple equipment.To guarantee the users'comfort and power fairness,the number of energy blocks for each device is allocated to avoid long-term consumption of power resources by the device.Combining voltage difference and time slot delay,a fast sensing distributed active control strategy is designed for voltage fluctuations.Simulation results show that this method can achieve orderly load control,smooth load curves,and reduce the peak-to-valley difference.
