The invention provides a distribution network-micro-grid multi-agent distributed collaborative optimization method and equipment, and the method comprises the steps: constructing a
safe operation model of a distribution network-micro-
grid system, and building a multi-stage optimization model with the minimization of the operation cost as a target based on the model, a multi-stage optimization model is decomposed into an active power distribution network operator optimization sub-problem and a plurality of micro-
grid operator optimization sub-problems, and a distributed optimization
algorithm is designed based on an augmented Lagrange function and a consistent alternating direction
multiplier method, so that each main body iteratively updates a local decision variable, a shared variable copy and a
Lagrange multiplier, and the optimal power distribution network operator optimization sub-problem is obtained. Collaborative optimization solution is realized; based on a distributed optimization
algorithm, a rolling
time domain optimization framework is adopted to realize real-time cooperative operation and reactive power support regulation and control of the distribution network and the
microgrid. Based on the method, the invention further provides distribution network-
microgrid multi-agent distributed collaborative optimization equipment. According to the invention,
safe operation of the distribution network and the micro-grid is guaranteed, the reactive power support capability of the
system is improved, and the operation cost is reduced.
