Feasible region optimization analysis method for distributed energy generation plan

Abstract

The present invention relates to a feasible region optimization analysis method for distributed energy generation plan, including step 1): establishing a simplified economic dispatch DC linear model of distributed energy system; step 2): drawing on the idea of ​​simplex two-stage method, Add artificial variable on the basis of described model, construct the optimization model of the first stage of two-stage method; Step 3): solve the first stage optimization model described in step 2, judge whether the former problem has solution; Step 4): use " linear The lagrange multiplier method under the cost function model or the simplex multiplier method can be used to obtain the lagrange multipliers of all effective unit output upper limit constraints and line capacity constraints. The beneficial effects of the present invention are: solving the problem of unavailability of power generation plan due to factors such as bad data and unreasonable constraints in the actual operation process; at the same time solving the problem of high power purchase costs caused by too strict constraints.

Description

technical field [0001] The invention relates to a technology in the field of distributed energy systems, in particular to an optimization analysis method for a feasible region of a distributed energy generation plan. Background technique [0002] With the large-scale access of distributed energy resources, the transaction optimization scheduling problem of energy systems becomes more complex. In the process of traditional power generation planning research, all the energy is concentrated on how to solve the power generation planning model, and the rationality and optimality of the model are less considered, which makes the power generation plan unsolvable, or the solution results do not meet the needs of actual dispatching and operation. The problems to be solved urgently in the entire intelligent dispatching planning system are: first, to provide auxiliary decision-making for operators to correct the model scientifically when the model is unreasonable; suggestion. Therefo...
