Abstract

The invention discloses a virtual power plant distributed model prediction control method under the active power distribution network environment, and belongs to the technical field of power system automatic control. A virtual power plant integral dynamic optimization model is established according to the distributed characteristic and the randomness characteristic of all energy resources; the integral dynamic optimization model is converted into subsystem models with all energy groups acting as main bodies according to the geographical distribution characteristics of all the distributed energy; and dynamic optimization of the output process of all the subsystem models is performed by adopting the distributed model prediction control method so that complexity of system optimization can be reduced and dynamic optimization configuration of the energy resources in a virtual power plant can also be realized.

Description

technical field [0001] The invention discloses a distributed model predictive control method of a virtual power plant under the environment of an active power distribution network, and belongs to the technical field of automatic control of electric power systems. Background technique [0002] With the large and extensive access of flexible loads in the active distribution network environment, the optimization problem of the distribution network system presents nonlinear and strong stochastic coupling characteristics. In order to better control distributed energy resources scattered in different regions , the introduction of the virtual power plant divides the original large-scale complex system into several subsystems, which greatly reduces the complexity of its optimal control. However, the general virtual power plant optimization method cannot fully consider the random characteristics of each distributed energy source in the virtual power plant, which makes the optimizatio...
