Embodiment Construction

[0045] The present invention will be further described below in conjunction with the drawings. The following embodiments are only used to illustrate the technical solutions of the present invention more clearly, and cannot be used 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, it integrates electricity price information and indoor and outdoor environmental temperature information to predict and regulate electricity, cold, and heat loads. Renewable energy, main grid, combined heat and power equipment, boilers and other energy forms complement each other and highly coordinated control of "source-grid-load-storage" links. With the help of various energy conversion devices, the energy supply and demand in the region will be balan...

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 of a multi-energy complementary system. Background technique [0002] With the rapid economic development and the rapid rise of the energy Internet industry, intelligent electrical equipment is highly popularized, the randomness of the supply side is increased, the controllability is reduced, the demand side requires more efficient and clean, and the demand side volatility increases. Security risks have increased, and the integrity has become more prominent. Summary 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 the safe and stable operating conditions of the system, the optimal utilization of resources is considered and the system operating cost is minimized. [0004] T...
