Multi-energy virtual power plant operating parameter aggregation method based on robust correction

Abstract

The invention relates to a multi-energy virtual power plant operation parameter aggregation method based on robust correction, and belongs to the technical field of operation control of comprehensiveenergy systems. According to the method, the comprehensive energy system within a certain range is equivalent to a model similar to a generator, is connected with the power system through a tie line and participates in power system dispatching, and regulation and control of a power system dispatching center are facilitated. The multi-energy virtual power plant model formed by modeling comprises power baseline and power upper and lower limit constraints, energy upper and lower limit constraints and power variation upper and lower limit constraints, and the model ensures that any day-ahead scheduling plan issued by a power system scheduling center and meeting all constraints of the model can be realized by virtual power plant tracking. According to the method, it can be guaranteed that any power system dispatching plan within the model range can be followed by the multi-energy virtual power plant, so that the executability of the power system dispatching plan is guaranteed, and the method can be used in an actual power system and has good expandability.

Description

technical field [0001] The invention relates to a multi-energy virtual power plant operation parameter aggregation method based on robust correction, and belongs to the technical field of operation control of integrated energy systems. Background technique [0002] In recent years, the proportion of new energy power generation in the power system has been increasing year by year. The characteristics of randomness, intermittency, and volatility of new energy power generation have brought new challenges to the operation of the power system. The power system urgently needs to explore new flexibility to reduce new energy. The impact of energy randomness. [0003] Virtual power plant is a concept that has emerged in recent years. Virtual power plant refers to the aggregation and coordination optimization of distributed resources that are difficult to directly control by the power system itself, such as distributed power generation, batteries, controllable loads, and electric vehi...

However, this aggregation method does not consider a variety of energy conversion equipment in the virtual power plant, such as cogeneration units and electric boilers, and does not consider the characteristics of the maximum and minimum active power of the virtual power plant that may change over time, so the aggregation method is too large. Conservative, losing some flexibility
