Detailed ways

The specific implementation of the utility model is described in detail below in conjunction with the drawings and specific circumstances.

In conjunction with the accompanying drawings, a smart energy management system for renewable energy is provided, including a water pump and a hydropower station. The system combines power generation of multiple renewable energy sources. The water inlet of the hydropower station 4 is connected to the water outlet of the upper reservoir 1, the water outlet of the hydropower station 4 is connected to the water inlet of the lower reservoir 2, the water outlet of the lower reservoir 2 is connected to the water inlet of the upper reservoir 1 via a water pump 3, the power output ends of the hydropower station 4, the solar power generator set 9 and the wind power generator set 10 are respectively connected to the energy management system 5, and the power output ends of the energy management system 5 are respectively connected to the water pump 3 and the distribution network 7.

To ensure better implementation effects, the power input end of the energy management system 5 is connected to the power output ends of the generator 6 and the energy storage element 8 respectively.

The energy storage element 8 is a battery energy storage element.

The energy management system 5 is a controller.

The controller is a PLC controller.

During the specific operation of the utility model, the solar power generator set 9 and the wind power generator set 10 generate electricity and transmit the electricity to the energy management system 5, and the energy management system 5 transmits the electricity to the water pump 3. When the power grid is under low load, the surplus electricity of solar energy and wind energy is used to start the water pump 3, transport the water in the lower reservoir 2 to the upper reservoir 1 and store it for standby; when the power grid is under high load, the water in the upper reservoir 1 is released to drive the turbine in the hydropower station 4 to generate electricity, and transmit the electricity to the energy management system 5, the energy management system 5 sends the electricity to the consumer through the distribution network 7, the generator 6 also generates electricity in unforeseen circumstances to support the peak of electricity consumption, and the energy storage element 8 can provide energy to the energy management system 5. The system uses a "natural" battery system, that is, pumped storage energy storage. When the surplus electricity is obtained from renewable energy, the water in the lower reservoir 2 is sent to the upper reservoir 1 through the water pump 3, so that the efficiency of the energy management system is maximized.

The utility model includes a simulation mode and an automatic mode (a function of the controller itself). The simulation mode is used to obtain the optimal size ratio of all power generation elements (solar generator sets, wind power generator sets, hydropower stations) or storage elements (energy storage elements). The automatic mode is used to control all elements, such as start and stop valves and actuators, to couple the energy in the microgrid and monitor its parameters, and to accurately analyze and process data of renewable energy. The data collected by the system can be monitored in real time, and early warning and recording actions can be made, making the energy management system more intelligent and running safer and more stable. By using the simulation mode in the energy management system, the production and storage energy capacity of each element can be effectively adjusted.

The utility model has a simple structure and comprehensive functions. Compared with the prior art, it has the following advantages:

1. The energy management system can obtain surplus energy from wind and solar energy. Through the action of water pumps, water from the lower reservoir is pumped to the upper reservoir for energy storage, and can also be used to generate electricity when necessary;

2. The energy management system includes three renewable energy sources: solar, wind and hydroelectric power, and two energy storage solutions: energy storage elements and pumped storage, which can improve the efficiency of the energy management system;

3. With the help of renewable energy and pumped storage, energy is produced and stored at a lower cost, solving the power supply needs of remote areas that cannot be connected to the national energy system or have low power quality;

4. The energy management system no longer generates energy consumption costs from the main power grid, but only generates operation and maintenance costs of system components. It is economical and can produce and store energy at a lower cost. When energy consumption exceeds the production level, the system uses stored energy for user consumption. Each generator set and energy storage module can be fully utilized, generating electricity safely and economically, improving the overall system efficiency, improving system performance and reliability, reducing energy costs, and having good social and economic benefits.

It should be pointed out that the above is only a preferred embodiment of the utility model, and does not impose any form of limitation on the utility model. Any technician familiar with the profession can use the technical content disclosed above to make changes or modify them into equivalent embodiments with equivalent changes without departing from the technical solution of the utility model, which all fall within the protection scope of the utility model.
