A real-time dispatching plan adjustment method for regional power grid

Abstract

The invention relates to a regional power grid real-time scheduling plan adjustment method. The method comprises the following steps: acquiring peripheral data; acquiring a planned output of a unit of each province from an uploaded data file of a provincial dispatching unit; in consideration of a super short period load of each province, acquiring a real-time generation scheduling deviation; acquiring an assessment index according to the plan execution condition of each province; calculating a deviation automatic distribution coefficient of each province according to the assessment index; respectively calculating a network dispatching deviation and a provincial dispatching deviation of each province, and equally distributing the network dispatching deviation to each unit. The regional power grid real-time scheduling plan adjustment method provided by the invention effectively achieves an application of provincial power grid information in the real-time scheduling plan work, and enhances the flexibility and controllability of the real-time scheduling plan.

Description

technical field [0001] The invention relates to the field of electric power system dispatching plan, in particular to a method for adjusting a real-time dispatching plan of a regional power grid. Background technique [0002] At present, the real-time power generation plan based on the smart grid dispatching technical support system has been put into actual production and operation, but the real-time plan information such as the provincial hydropower plan, thermal power plan, and unit performance is not fully grasped by the network dispatcher, and the real-time dispatching information sharing is insufficient; due to information sharing Insufficient, compared with day-ahead and intra-day planning models and compilation algorithms, real-time planning is relatively simple; the data feedback and human-computer interaction of real-time planning are insufficient, and the reference information provided to users is less. [0003] Due to the particularity of the dispatching relations...

[0002] At present, the real-time power generation plan based on the smart grid dispatching technical support system has been put into actual production and operation, but the real-time plan information such as the provincial hydropower plan, thermal power plan, and unit performance is not fully grasped by the network dispatcher, and the real-time dispatching information sharing is insufficient; due to information sharing Insufficient, the real-time plan is relatively simple compared with the day-ahead and intraday plan model and compilation algorithm; the data feedback and human-computer interaction of the real-time plan are insufficient, and the reference information provided to users is less

[0003] Due to the particularity of the dispatching relationship between the regional power grid and the provinces and cities under its jurisdiction, that is, the same balancing area is jointly balanced by the grid dispatcher and the provincial dispatcher. The current real-time power generation plan has not been approved by the provincial dispatcher. The daily plans for water and thermal power of the units, the adjustment performance of the units, etc. Scheduling plan information, which leads to asymmetric information acquisition, it is difficult to achieve fairness, justice, and openness in the design of real-time planning models and algorithms, and in special extreme cases, it will directly affect the safe and reliable dispatching of the power grid
