The invention discloses an
optimal scheduling method and platform for distributed collaborative mutual aid of multiple
virtual power plants, relates to the technical field of intelligent scheduling of power systems, and is used for solving the problems of limited data privacy, slow optimization convergence and opaque transaction execution among the existing multiple
virtual power plants. The method comprises the following steps: firstly, calculating power generation cost increments under different output levels according to
wind power and photovoltaic output prediction and load demand prediction data of each
virtual power plant, and generating a quotation curve reflecting transaction willingness; then, each
virtual power plant quotation curve is used as an input, a distribution
network topology parameter and a line capacity constraint are combined, a distributed collaborative optimization model based on Lagrangian relaxation is constructed, and parallel solving of local
power optimization and
coordination layer dual updating is realized; in the
iteration process, a
penalty factor is adaptively adjusted through the ratio of an original residual error to a dual residual error, and the stability and convergence efficiency of the
algorithm are improved; after optimization convergence, the mutual aid power and the
transaction price are written into a block chain intelligent contract, settlement and deviation punishment are automatically executed based on metering data on the chain, and a closed-loop
scheduling system from distributed optimization to trusted execution is constructed.
