Abstract

The invention relates to a microgrid economic optimal operation design method with a demand response included. The method comprises the following steps: 1) a microgrid optimal design database is built; 2) an optimization model is built, wherein the objective function for the optimization model is the minimum total cost of the microgrid operation, and constraint conditions comprise a power balance constraint, a controllable unit output constraint, a controllable unit ramp constraint, a tie line transmission power constraint and a controllable load capacity constraint; 3) the input variable parameter value needed by the optimization model is acquired from the microgrid optimal design database, an improved genetic algorithm based on chaos optimization is adopted to solve the optimization model, and output data of a decision variable of the optimization model are acquired; and 4) the total microgrid operation costs under all scenes are compared according to the output data of the decision variable, and the optimal scene and the corresponding interruptible load optimal control strategy can be acquired. Compared with the prior art, the method of the invention realizes more reasonable, more economic and more efficient mircrogrid energy utilization from aspects of a demand side and management operation.

Description

technical field [0001] The invention relates to a microgrid operation optimization method, in particular to a microgrid economic optimization operation design method including demand response. Background technique [0002] The market-oriented reform of electricity has brought new challenges to the implementation of demand-side management in the power industry. The benefits brought by the implementation of demand-side management under the original vertical monopoly system to power companies have been dispersed. Some traditional demand-side management measures such as load management and energy efficiency The basis for implementation has also changed. With the development and improvement of the competitive market, the stakeholders of the power system are gradually diversified, and the role of demand-side resources in the competitive market is being re-recognized. [0003] Demand response is the development of demand side management in competitive electricity markets. Using p...
