Problems solved by technology

Since distributed renewable energy is directly connected to the grid, it is easy to cause problems such as overvoltage and congestion. In addition, its power generation output is random and volatile and the load rate is poor at the same time. Grid companies have adopted various measures to limit distributed renewable energy to the grid. measures, resulting in a large amount of abandoned power generation

Embodiment Construction

[0076] The principles and features of the present invention will be described below with reference to the accompanying drawings. The examples are only used to explain the present invention, but not to limit the scope of the present invention.

[0077] For such as figure 1 The micro-net community system shown in the present invention adopts the method of three optimizations and three clearings under the framework of the multi-agent system. This paper establishes a three-layer interactive market with an alternate iteration algorithm as the core. Each layer of the three-layer iteration carries out real-time electricity price settlement. From local to overall, it seeks to maximize the benefits of microgrids, aggregators, and microgrid communities. , at each stage of the iteration, distributed resource owners and aggregators can calculate profits through the method proposed in this paper, making the market clearing process clearer, so that distributed resources can adapt to the unc...

Abstract

The invention relates to a distributed resource transaction method of a microgrid community under a multi-agent framework. The method includes three iterative electricity price clearing layers. The first layer is used for operating optimization calculation in the microgrid. The second layer is used for operating scheduling optimization calculation in an aggregator. The third layer is used for transaction calculation between the aggregators. Each of the three iterative electricity price clearing layers performs real-time electricity price settlement, and achieves, from local to overall, benefit maximization of the microgrid, the aggregators, and the microgrid community respectively. In each phase of the iteration, distributed resource owners and the aggregators can calculate profits by the method in the present invention, thereby making the market clearing process clearer. The mode optimizes the configuration of distributed resources within the microgrid community while ensuring the benefits of all market participants, thereby ensuring the safety of each microgrid, ensuring the reasonable income for the distributed resource owners, and enhancing the overall balance capacity of renewable energy by price excitation.

Description

technical field [0001] The invention relates to the fields of resource allocation and electricity market, in particular to a distributed resource transaction method for a micro-grid community under a multi-agent framework. Background technique [0002] With the country's emphasis on renewable energy and the introduction of a series of policies, distributed renewable energy has ushered in rapid development. Because distributed renewable energy is directly connected to the power grid, it is easy to cause problems such as overvoltage and blockage. In addition, its power generation output has strong randomness and volatility, and the load simultaneity rate is poor. measures, resulting in a large amount of abandoned power generation. [0003] A microgrid community is a microgrid cluster composed of multiple microgrids connected to the same feeder and containing distributed resources (DERs). DG), energy storage system (ESS) and flexible load (Price-responsive Load, PRL); and the...
