Problems solved by technology

Due to the small capacity of distributed power sources such as energy storage and photovoltaics, the existing micro-grid system has a small load on the micro-grid, and the AC system and DC system are relatively scattered, lacking a unified coordinated control platform and strategy, and the micro-grid operating mode is simple. It can take advantage of the complementary advantages of source, grid, load and storage, and the economy and reliability of the microgrid are relatively low

Embodiment

[0030] This embodiment proposes a microgrid control method for multi-energy flow complementary control, refer to figure 1 ,include:

[0031] S1, on-site consumption of distributed energy in the micro-energy network;

[0032] Step S1 specifically includes: using energy storage devices to consume distributed energy:

[0033] S101, when the output load of the distributed power supply is greater than the base load during the day, charge the energy storage device, and determine whether the area where the energy storage device is located is covered by a trading market, if it is, enter step S102, if not, enter step S103;

[0034] S102. Publish charging preferential information to the periphery of the area;

[0035] S103, when the photovoltaic no longer outputs load at night, the energy storage device discharges.

[0036] When the light resources are good, the distributed power generation will have relatively sufficient power generation capacity. The operator of the micro-energy ne...

Abstract

The invention provides a microgrid control method for multi-energy-flow complementary control. The method comprises the following steps: S1, locally consuming distributed energy of a microgrid; S2, carrying out peak clipping and valley filling of the AC / DC microgrid, and charging and carrying out discharging control through the charging and discharging time periods of a planned curve and the charging and discharging power values corresponding to the charging and discharging time periods according to a planned curve mode; and S3, freely switching between a grid-connected state and an off-grid state of the alternating-current and direct-current microgrid. Coordinated control over sources, networks, loads and storage of substations, data center stations, high-capacity comprehensive energy stations and the like is achieved, the big data mining technology is utilized, the operation strategy is adjusted in real time, the advantages of source, network, load and storage complementation are brought into full play, and the reliability of the microgrid and the comprehensive benefits of a power grid are improved.

Description

technical field [0001] The invention relates to the technical field of micro-grid control, in particular to a micro-grid control method and system for multi-energy flow complementary control. Background technique [0002] my country is facing an "energy comprehensive era" in which new energy and fossil energy complement each other. Under the energy demand in the new era, my country urgently needs to take a new round of technological revolution and industrial revolution as the fulcrum, and change from the previous extensive development model to a more intensive one. , sustainable development model, and establish a more efficient, safe and sustainable energy utilization model. The distributed energy system provides an effective way for commercial or industrial users who need cold, heat, and electricity, as well as island power supply and mobile power supply, but the energy utilization method of the distributed energy system is distributed "in-situ collection, on-site storage, o...
