Embodiment Construction

[0045] The present invention will be further described below in conjunction with the accompanying drawings. The following examples are only used to illustrate the technical solution of the present invention more clearly, but not to limit the protection scope of the present invention.

[0046] figure 1 The power flow composition diagram of the multi-energy complementary system is given. figure 1 The multi-energy complementary system is divided into two parts: electricity flow and heat flow. With the help of information technology, electricity price information and indoor and outdoor environment temperature information are integrated to predict and regulate electricity, cooling, and heat loads respectively. Renewable energy, the main power grid, cogeneration devices, boilers and other forms of complementary energy and highly coordinated control of the "source-network-load-storage" link, with the help of various energy conversion devices, ultimately achieve a balance between ene...

Abstract

The invention discloses a coordinated control method of a multi-energy complementary system, which comprises the following steps: in a day-ahead scheduling stage, determining a start-stop period of adevice with a large inertia link through a day-ahead robust optimal scheduling based on a long-time prediction information of the next day; in the intra-day scheduling stage, determining the output power of the continuously adjustable device by intra-day multi-objective quantum particle swarm optimization based on intra-day short-time prediction information; by using the cooperative optimization of day-ahead and day-within-day scheduling, finally determining the operation mode of the multi-energy complementary system, and realizing the coordinated control of the multi-energy complementary system. While guaranteeing the safe and stable operation condition of the system, the method considers the optimal utilization of resources and realizes the minimum operation cost of the system.

Description

technical field [0001] The invention relates to the technical field of energy coordinated control, in particular to a coordinated control method for a multi-energy complementary system. Background technique [0002] With the rapid development of the economy, the rapid rise of the energy Internet industry, the high popularity of smart electrical equipment, the randomness of the supply side is enhanced, the controllability is reduced, the demand side is required to be more efficient and clean, and the volatility of the demand side is increasing. Security risks are increasing, and the integrity is highlighted. Contents of the invention [0003] The purpose of the present invention is to overcome the deficiencies in the prior art and provide a coordinated control method for a multi-energy complementary system. On the basis of ensuring safe and stable operating conditions of the system, the optimal utilization of resources is considered to realize the minimum operating cost of ...
