Small electric energy management and coordination control integrated device

Abstract

The invention discloses a small electric energy management and coordination control integrated device, relates to the fields of new energy power generation, electric vehicle charging and discharging,battery energy storage and electric energy management and coordination control for household indoor power supply networks, and belongs to the field of household electric energy control and managementfor novel power utilization equipment, new energy power generation equipment, electric automobiles and the like. An energy management and control unit in the device acquires the information sent fromeach AC / DC module, each DC / DC module and a controller of AC / DC / AC modules in real time. On the above basis, the output characteristics of each distributed energy source are analyzed, and the power balance requirements of the power generation side and the demand side are pre-judged. The state change of the energy flow among all equipment is evaluated. After that, through the optimal scheduling calculation, all modules are coordinated and controlled to run efficiently. Therefore, the effective flow of energy is achieved. In this way, on the premise that the entire device and external electric equipment are ensured to run stably and safely, the electric energy generated by wind power generation and solar power generation is fully utilized. The purposes of energy conservation and environmentalprotection are achieved. Economic benefits are brought to users.

Description

Technical field [0001] The invention relates to electric energy management and coordinated control of new energy power generation, electric vehicle charging and discharging, battery energy storage, and household power supply networks, and belongs to the field of household electric energy control and management including new energy power generation equipment, electric vehicles and other new electrical equipment. Background technique [0002] With the development of the national economy, the demand for electricity is increasing. In the future global energy Internet, there will be a large number of new energy power generation equipment such as wind energy and solar energy, as well as new electric equipment such as electric vehicles that can perform two-way conversion of energy. A considerable number of these devices are not centrally managed, so the energy Internet must solve the problem of the operation of a large number of distributed power sources in the distribution network.

Problems solved by technology

[0007] The ultra-small power grid system with households or buildings as power consumption units usually also includes various power generation and power consumption equipment such as photovoltaic power generation, wind power generation, and electric vehicles. The interconnection and collaborative work of various devices in the network will be due to the scattered modules and different types and specifications of the devices, making the networking process complicated and not easy to maintain and upgrade

At the same time, the coordinated working ability is poor, and it is impossible to effectively and dynamically optimize the management of energy flow at the system level, and it is difficult to achieve optimal operating efficiency.
