Abstract

The invention belongs to the field of smart power grids, and provides a distributed differential privacy ADMM energy management and control method and system for a smart power grid. The method comprises the following steps: acquiring relevant parameters of heterogeneous power generation equipment and a demand response unit in a smart power grid; on the basis of the obtained parameters, a distributed differential privacy ADMM algorithm and a pre-constructed target function, the optimized output power of the heterogeneous power generation equipment and the consumption power of the demand response unit are obtained; wherein the target function is constructed based on the power generation cost function of the heterogeneous power generation equipment, the utility function of the demand response unit, the constraint condition and the transmission loss of the heterogeneous power generation equipment and the demand response unit with social welfare maximization.

Description

technical field [0001] The invention belongs to the field of smart grids, and in particular relates to a distributed differential privacy ADMM energy management and control method and system for smart grids. Background technique [0002] The statements in this section merely provide background information related to the present invention and do not necessarily constitute prior art. [0003] The smart grid is the main part of the third generation grid. As a typical physical-information-social system, it not only has the physical characteristics of the traditional grid, but also integrates the information and social attributes of the future grid. In one highly automated system. The safe and healthy development of smart grid is of great significance to the rational allocation of energy structure. However, the unstable and uncontrollable characteristics of wind power generation bring great challenges to the energy management of the grid. [0004] As the scale of the power gri...
