Embodiment Construction

[0057] The present invention will be further described below in conjunction with the accompanying drawings.

[0058] A schematic diagram of a typical factory integrated energy system is shown in figure 1 As shown, m groups of photovoltaic power generation systems, batteries and / or DC loads are respectively connected to m DC buses, connected to the common AC bus through bidirectional converters, and the AC bus is equipped with a cold storage device. Then the AC bus is connected to the distribution network through the transformer. The system can meet both DC load demand and AC load demand. The whole system can be divided into DC power supply, DC load and AC power supply, AC load. The local DC bus is used to connect the DC energy equipment and connect to the AC system through a bidirectional converter. This structure enables batteries and DC loads to use the energy output from photovoltaics before AC and DC conversion. By eliminating unnecessary energy loss during AC-DC conve...

Abstract

The invention discloses an integrated demand response method considering interaction of an industrial park and a factory. The method comprises the steps of firstly, constructing an integrated energy system model of the factory, and constructing an integrated demand response (IDR) model considering automatic optimization of the factory by taking minimum power utilization cost of a user as a target under the condition of considering power utilization satisfaction of the user and load fluctuation of a system so that automatic optimization dispatching of the factory is achieved and is used as a basis participating in interaction; and secondly, performing dispatching of the industrial park and information interaction among factory control systems, further mining and utilizing controllable capability of distributed resources such as sources, storage and loads of each factory in the park at a level of the whole park region, building the IDR model for interaction of the industrial park and the factory according to a gate power of the park region being within a limit and minimum energy utilization cost of the user, and responding upper-level power grid demand.

Description

Technical field [0001] The invention relates to a comprehensive demand response that takes into account the interaction between industrial parks and factories, and belongs to the field of comprehensive energy and power demand response. Background technique [0002] In the context of the Energy Internet, the decentralized energy market and energy network structure make traditional power demand response (DR) gradually develop into integrated demand response (IDR). Industrial parks have become a good platform for IDR implementation due to their characteristics such as increasing energy demand, multiple energy types, unreasonable energy structure, reduced conventional energy reserves, generally low energy utilization rates, and large peak-valley power load differences. If only the self-optimizing operation of factories in industrial parks is considered, new load peaks may occur, which cannot meet the peak load regulation needs of the superior power grid. Therefore, it is necess...
