Abstract

The invention discloses a multi-scene based regional energy internet source charge storage dual-stage coordination optimization method, which comprises the following steps: firstly, establishing a mathematical model of each unit and demand side response according to the operation characteristics of each unit and the response traits of the demand side in the regional energy internet system; secondly, generating a random scene set according to the indefinite variables; thirdly, according to the prior day random scene set, constructing a prior day optimizing and dispatching model with the best total social welfare as the target, determining the electricity price for the next day, the starting up and shutdown state of each unit, and the operation output plan; finally, constructing the intradayoptimizing and dispatching model with the aim of lowest operation cost, amending the operation output plan of every unit and determine the intraday operating power and power storage system charge-discharge power of each unit. The method in the application improves the reliability, the stability and the robustness of the operation of the regional energy internet system.

Description

technical field [0001] This application relates to the technical field of multi-energy coordination and optimization in the regional energy Internet system, in particular to a multi-scenario-based source-load-storage two-stage coordination and optimization method for regional energy Internet. Background technique [0002] The regional energy Internet system is an energy system with the power system as the core. It uses energy storage and conversion technologies to tightly couple different energy systems such as power grids, cooling and heating networks, and natural gas pipeline networks. Various resources such as renewable energy, energy storage, combined cooling, heating and power supply, etc., coordinate and optimize management of different energy systems, so as to realize complementary supply and coordinated operation of various energy sources such as cooling, heating, electricity, gas, and renewable energy. Therefore, The regional energy Internet system plays a very impo...
