Distributed energy resource dispatching method and system for interactive energy resource system

Abstract

The invention is suitable for the technical field of energy resource dispatching, and provides a distributed energy resource dispatching method. The method comprises the steps of building a cost modelaccording to the type of a distributed energy resource, performing modeling according to a price factor and a prediction error to obtain a price model and an error model, and building a day-ahead dispatching model according to the cost model, the price model and the error model based on maximized total profits of a day-ahead market; based on a minimized unbalanced cost, building a real-time dispatching model according to an unbalanced cost model; and solving the day-ahead dispatching model to obtain a first optimization result, solving the real-time dispatching model according to the first optimization result to obtain a second optimization result, and performing distributed energy resource dispatching according to the second optimization result. According to the dispatching method and system, a virtual power plant is assisted to make a trading or dispatching policy and know the problem of the market risk.

Description

technical field [0001] The invention belongs to the technical field of energy scheduling, and in particular relates to a distributed energy scheduling method and method for an interactive energy system. Background technique [0002] The penetration of renewable energy in the global electricity system is increasing. However, intermittency means that the integration of renewable energy into the grid relies on various forms of distributed energy, such as distributed renewable energy generation (such as wind and solar), distributed non-renewable energy (such as gas turbines), energy storage systems Wait. [0003] It has recently been suggested that interactive energy systems can be used to facilitate energy transactions between distributed generation and electricity markets, as more and more consumers are becoming "prosumers" (i.e., consuming and producing energy). As an agent in the retail market, a Virtual Power Plant (VPP) pools the capacity of many distributed generation a...
