Description

一种面向用户负荷特异性的热电协同调度系统和方法A user load specificity-oriented thermoelectric coordinated scheduling system and method

技术领域technical field

本发明涉及电力系统分析技术领域，具体涉及一种面向用户负荷特异性的热电协同调度系统和方法。The invention relates to the technical field of power system analysis, in particular to a user load specificity-oriented thermoelectric coordinated scheduling system and method.

背景技术Background technique

随着经济的飞速发展和一次能源日益枯竭，以及环境污染问题的如意突出，绿色可再生能源越来越受到各国的关注。我国风电的装机容量和并网规模逐年增大，但同时也面临着严重的弃风现象。有相关研究表明，我国三北地区多风期与供暖高峰期相重合，热电厂在供暖期因供暖而导致系统调峰能力急剧下降是导致弃风的一个主要原因。With the rapid development of the economy, the depletion of primary energy, and the prominence of environmental pollution, green renewable energy has attracted more and more attention from all countries. The installed capacity and grid-connected scale of wind power in my country are increasing year by year, but at the same time, it is also facing serious wind curtailment. Relevant studies have shown that the windy period in the Three North Regions of my country coincides with the heating peak period, and the sharp decline in the peak regulation capacity of the thermal power plant due to heating during the heating period is one of the main reasons for the abandonment of wind.

传统的“以热定电”运行模式限制了热电联产机组的电出力调节范围，使系统的调峰能力下降，进而降低了系统对风电资源的接纳能力，造成大量弃风；同时，现有调峰系统忽略不同用户的差异性也能参与所能提供的潜在电力调节能力，进而提高热电联产的灵活性及可再生能源的消纳能力的问题。The traditional operation mode of "determining electricity by heat" limits the power output adjustment range of the cogeneration unit, which reduces the peak shaving capability of the system, which in turn reduces the system's ability to accommodate wind power resources, resulting in a large number of wind curtailments; at the same time, the existing The peak shaving system ignores the differences of different users and can also participate in the potential power regulation capacity that can be provided, thereby improving the flexibility of cogeneration and the ability to absorb renewable energy.

有鉴于此，亟需提供一种优化用户差异性导致的负荷与蓄能的配合的方法及系统。In view of this, there is an urgent need to provide a method and system for optimizing the coordination of load and energy storage caused by user differences.
