Embodiment Construction

[0035] It will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0036] figure 1 It is a schematic diagram of the model of the land-saving two-level "air-water" bundling control system of the present invention, and the establishment of the control system can be based on the following steps:

[0037] Step 1. Establish a main control area in the AGC application of the provincial dispatching center, which is used to implement the conventional regional control of the provincial interconnected grid. The control goal is to maintain the frequency of the grid within the control range, or to maintain The exchange power between this control area and other adjacent control areas is a given planned value, or the above two control objectives are met at the same time;

[0038] Step 2: Establish a "wind-water" bundling control area in the AGC application of the regional dispatching center inside the provincial power grid, which is used to i...

Abstract

The invention discloses a system and a method for AGC coordination control on transmission of bundled wind-hydropower. The system comprises a provincial power dispatching AGC main control region, multiple district power dispatching AGC bundled control regions, and bundled hydropower sets and bundled wind power sets which are respectively arranged in each district power dispatching AGC bundled control region and are respectively under the corresponding district power dispatching AGC control, wherein the district power dispatching AGC bundled control regions are used for carrying out bundled wind-hydropower control, the provincial power dispatching AGC is responsible for providing control targets for the district power dispatching AGC bundle-control control regions, the provincial power dispatching AGC main control region is used for controlling each district-level bundled wind-hydropower virtual simulation model, and control parameters of the virtual control object model are transmitted from the district power dispatching AGC. The method is about rules of different operation modes such as real-time ACE control, plan curve tracking, wind power fluctuation inhibition and generating index control participated by a bundled wind-hydropower virtual set. The system is advantaged in that a main hydropower and secondary wind power combined mode and a two-level provincial and district coordination control mode are employed, and two targets including the safe and stable effect of the power grid and the full wind power source utilization effect are realized.

Description

technical field [0001] The invention relates to the technical field of active power control of electric power systems, in particular to an AGC coordinated control system and control method suitable for bundling and sending out wind power and hydropower in regional power grids after large-scale wind power is connected to the grid. Background technique [0002] Wind power is currently the most mature technology and the best economic benefit of renewable energy power generation except hydropower. After the grid-connected operation of large-scale wind power, the impact of the randomness, volatility and intermittent characteristics of wind power on the safe and stable operation of the power grid has gradually emerged. With the start of construction of several 10-million-kilowatt-scale wind power bases in China, it is gradually becoming more difficult for the power grid to fully absorb wind power under the premise of ensuring safe and stable operation and active power control perf...
