This invention provides a residential aggregator-based optimal
energy management method, comprising the following steps: constructing an aggregator model, building generalized
energy storage models for three types of residential appliances—batteries,
HVAC systems, and electric vehicles—and aggregating them into a residential aggregator for
centralized management; generating
scheduling instructions for the aggregator, in the first decision-making stage, formalizing the optimization control process into a Markov
decision process, interacting with the environment based on the Soft Actor-Critic framework, learning the
optimal scheduling strategy, and tracking the upper-level
power grid scheduling while ensuring operational constraints; decomposing the aggregator's control instructions, in the second decision-making stage, the residential aggregator generates scheduling plans for each appliance through a three-step
decomposition algorithm to follow the aggregated power scheduling defined in the first decision-making stage. This invention achieves automated and integrated control of
residential energy, improves the integration and intelligence level of the
energy system, reduces operating costs, and enhances user comfort.
