Embodiment Construction

[0030] The source-grid-load coordination control system based on new energy consumption can be divided into the whole network optimization scheduling layer, the regional monitoring and coordination layer, the local monitoring and control layer, and the primary equipment layer in space. Each layer performs different tasks, among which

[0031] The network-wide optimal dispatching layer is composed of the computer system of the superior dispatching control center to realize the optimal dispatching of the entire network. The real-time operation data of power generation, power grid and load of the whole network are collected and processed through the power dispatching data network. On the basis of meeting the safe and stable operation requirements of the power grid, different time scales (long-term, medium-term, short-term and Ultra-short-term) optimal scheduling, to achieve the overall balance of power production capacity and load demand, and to maximize the overall economic and ...

Abstract

The invention discloses a new-energy-consumption-based source-grid-load coordination control method and system. On the basis of continuous increasing of a new energy scale and occurrence of a novel controllable load, overall cooperative dispatching is carried out on dispersed controllable loads in a region by using a multi-element coordination control technique, thereby realizing characteristic complementation between the several kinds of energy and controllable loads and thus realizing source-grid-load interaction. According to the invention, the new-energy-consumption-based source-grid-load coordination control system is divided into a whole network optimization scheduling layer, a regional monitoring and coordination layer, a local monitoring and control layer, and a primary equipment layer. With utilization of the network communication, data processing and coordinated control technologies, the system provides a technical base for a novel integrated operation mode of regional multi-energy power generation and production, load electricity usage and grid operation by taking improvement of the consumption capability of the new energy of the grid as an objective.

Description

technical field [0001] The invention relates to the field of power grid dispatching control, in particular to a source-grid-load coordination control method and system aiming at new energy consumption. technical background [0002] In a traditional power system, the power supply side is mainly composed of conventional power sources such as thermal power and hydropower, and the load side is mainly composed of uncontrollable conventional loads. Electric energy is transmitted from the power supply side to the load side through the power grid. The control system performs passive regulation. With the increase of my country's new energy development scale and the emergence of new controllable loads, the installed capacity of new energy in the "Three North" region is large and widely distributed, and the problem of new energy consumption is particularly prominent. Power grid regulation is facing new challenges. The traditional dispatching operation control mode It has been unable to...
