A Robust Correction-Based Multi-energy Virtual Power Plant Operational Parameter Aggregation Method

Abstract

The invention relates to a robust correction-based multi-energy virtual power plant operation parameter aggregation method, which belongs to the technical field of operation control of an integrated energy system. In this method, a comprehensive energy system within a certain range is equivalent to a model similar to a generator, which is connected to the power system through a tie line and participates in the power system dispatch, which is convenient for the power system dispatch center to control. The multi-energy virtual power plant model formed by the modeling of the present invention includes power baseline, power upper and lower limit constraints, energy upper and lower limit constraints, and power variation upper and lower limit constraints. The day-ahead scheduling plan can be tracked by the virtual power plant. The method of the invention can ensure that any power system dispatch plan within the model range can be followed by the multi-energy virtual power plant, thereby ensuring the executable power system dispatch plan, so that the method can be used in the actual power system, and has good feasibility Extensibility.

Description

technical field [0001] The invention relates to a robust correction-based multi-energy virtual power plant operation parameter aggregation method, which belongs to the technical field of operation control of an integrated energy system. Background technique [0002] In recent years, the proportion of new energy power generation in the power system has been increasing year by year. The random, intermittent and fluctuating characteristics of new energy power generation have brought new challenges to the operation of the power system. The power system needs to explore new flexibility to reduce new The impact of energy randomness. [0003] Virtual power plant is a concept emerging in recent years. Virtual power plant refers to the aggregation and coordination optimization of distributed resources that are difficult to be directly controlled by power systems such as distributed generation, storage batteries, controllable loads, and electric vehicles through advanced information a...

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
