Embodiment Construction

[0074] It should be understood that the specific embodiments described herein are only used to explain the present invention, but not to limit the present invention.

[0075] Because in the existing technology, the traditional multi-microgrid dispatching mechanism design requires deep professional knowledge and keen economic intuition, which is a complicated and difficult task. Whenever new application scenarios are added, economists need to adjust the principles accordingly. Having incentive mechanisms and designing new incentive mechanisms that can be applied to new application scenarios makes it difficult to design new incentive mechanisms quickly.

[0076] In order to solve the above-mentioned problems, the following embodiments of the present application use neural network technology to design a multi-micro-grid dispatching mechanism, thereby quickly and automatically designing an optimal multi-micro-grid dispatching mechanism suitable for various economic application scenarios...

Abstract

The invention discloses a microgrid power generation optimization method and system. The microgrid comprises an energy management center and a plurality of distributed power supplies, the microgrid power generation optimization method comprises the following steps that: each distributed power supply acquires the individual net power generation capacity of all the other distributed power supplies except the distributed power supply from the energy management center, and calculates the optimal translatable power generation capacity of the distributed power supply relative to all the other distributed power supplies under the condition of total income of the system according to a Nash equilibrium strategy; the energy management center determines the optimal translatable generating capacity ofeach distributed power supply relative to other distributed power supplies under the optimal system total income condition; and each distributed power supply adjusts the translatable power generationamount to the optimal translatable power generation amount according to the determination result of the energy management center. According to the technical scheme of the invention, the problems of mutual competition, unbalanced power generation and low income of distributed power supplies can be solved.

Description

Technical field [0001] The invention relates to a method and system for optimizing power generation of a micro-grid, and belongs to the technical field of micro-grid. Background technique [0002] Microgrid, also known as microgrid, refers to a small power generation and distribution system composed of distributed power sources, energy storage devices, energy conversion devices, loads, monitoring and protection devices, etc. The microgrid aims to realize the flexible and efficient application of distributed power sources, and solve the problem of a large number of distributed power sources connected to the grid in various forms. [0003] The microgrid can be connected to the distribution network, through its own distributed power supply, and delivered to the user side through the distribution network, so as to achieve a highly reliable supply of load on the user side. The development and extension of microgrids can fully promote the large-scale integration of distributed power sou...
