Abstract

The invention discloses a distributed power supply energy efficiency optimization method and system. Scheduling control is carried out from a day-ahead time scale and a day time scale, and modeling and optimization are respectively carried out on the two phases. A load is divided into an uncontrollable load, a translational load and a reducible load, an optimization model takes minimization of the sum of an energy storage cost in a scheduling period, an interaction cost with an upper power grid and a load cost as a target, features of a distributed power supply, energy storage and multi-element loads are taken into integrated consideration, interactive links among the three are enhanced, good interaction between a generating side and a load side is realized, and while regenerative energy is fully utilized, the integrated utilization efficiency of energy is improved.

Description

technical field [0001] The invention belongs to the field of electric power system and its automation. Background technique [0002] With the large-scale application of distributed power, the proportion of random, fluctuating and intermittent small distributed energy in my country's power grid will become larger and larger in the future, and will even become an indispensable part of the power grid. Integrating a variety of complementary distributed power sources into the grid and constructing a small multi-energy complementary distributed power station with plug-and-play capabilities will provide an effective solution for the integration of a large number of miniaturized distributed power sources into the Energy Internet. However, there is not yet a mature technical solution capable of realizing the above functions. Contents of the invention [0003] The purpose of the present invention is to optimize the scheduling of distributed power sources, energy storage and differe...
