Problems solved by technology

At present, the degree of openness of my country's electricity market is relatively low, and the construction of micro-grids has just started. It is still difficult for flexible loads to directly become the dispatching objects of large power grids or micro-grids in a short period of time, and to absorb wind power in a large area.
In addition, because the high-energy loads represented by the timber industry have strong adjustment capabilities, some studies have proposed a joint operation model of high-energy loads and wind power, using high-energy loads to absorb wind power locally, but high-energy loads The load is limited by geographical distribution, and the scope of application of the model is small

Embodiment Construction

[0047] A preferred example will be described in detail below in conjunction with the accompanying drawings. It should be emphasized that the following description is only exemplary and not intended to limit the scope of the invention and its application.

[0048] figure 1 The overall flowchart of the flexible load dispatching model under the cooperative operation mode of the load aggregator and the wind farm provided by the present invention specifically includes the following steps:

[0049] Step 1: Taking the electric load under the jurisdiction of the load aggregator as the object, determine the flexibility of the load and the compensation standard:

[0050] S1: The load aggregator classifies the loads under its jurisdiction and determines the proportion of each type of load;

[0051] According to the ability or willingness to participate in demand response, loads are divided into two categories: fixed loads and flexible loads. Fixed loads are rigid loads that do not part...

Abstract

The invention provides a flexible load scheduling model in a load aggregator and wind power farm coordinate operation mode. The model includes the steps: (1) taking power load governed by a load aggregator as an object to determining flexibility of the load; (2) building the load aggregator and wind power farm coordinate operation mode; (3) taking the consumption requirement of a wind power farm as a basis by a load aggregator, taking a maximum benefit as a goal and building a day-ahead optimal scheduling model. The model is beneficial to guidance of the load aggregator to aggregate the flexible load to participate in a power market, so that wind power consumption level is improved, and all-win of the wind power farm, the load aggregator and a user is realized.

Description

technical field [0001] The invention relates to the field of demand response, in particular to a flexible load dispatching model under the cooperative operation mode of a load aggregator and a wind farm. Background technique [0002] In recent years, in order to improve the energy structure and promote the sustainable development of society, my country has vigorously developed wind power generation. Due to the randomness, intermittence and obvious anti-peaking characteristics of wind power output, large-scale wind power grid integration has brought difficulties to the operation and scheduling of power systems. In the traditional dispatching mode, the load is passive and rigid, so the power supply mainly tracks the load to ensure the real-time balance of grid power. However, my country's power source structure is dominated by thermal power. There are few flexible power sources with fast response capabilities such as hydropower and gas units, and insufficient peak shaving res...
