Description

Technical Field

[0001] The present invention relates to the technical field of energy internet, and in particular to an intelligent energy routing system for energy internet. Background Art

[0002] With the rapid development of the global economy, energy demand continues to rise, the increasing depletion of traditional fossil energy and the environmental pollution problems it brings have prompted countries around the world to accelerate the transition to renewable energy. Distributed energy such as solar energy, wind energy, hydropower, and biomass energy are widely distributed and have great potential, but due to their diverse energy forms, large fluctuations in energy density, and strong intermittency, they bring many challenges to large-scale access and efficient utilization.

[0003] In the past, energy system architectures were mostly centralized, which made it difficult to adapt to the decentralization and complexity of distributed energy. They had drawbacks such as high energy conversion losses, lagging supply and demand regulation, and poor compatibility of different energy sources. For example, early solar photovoltaic power stations had limited solar energy collection efficiency due to the lack of precise tracking devices. They could only receive light at a fixed angle and could not be dynamically adjusted according to the position of the sun, resulting in a large amount of solar energy being wasted. Traditional energy storage devices lacked refined management, and charging and discharging were very random, resulting in a sharp drop in battery life and a significant reduction in energy storage effects. Grid dispatching relied on manual experience and was difficult to respond to complex and changing energy supply and demand in a timely manner, often causing local energy surpluses or shortages. The quality of electricity could not be guaranteed, and voltage fluctuations and harmonic interference occurred frequently, seriously affecting the life and stability of electrical equipment.

[0004] The concept of energy internet came into being, which advocates the construction of an open, interconnected and intelligent energy ecology, and requires the energy routing system to be like an intelligent transportation hub, accurately guiding the "torrent" of multiple energy sources. In this context, it is urgent to develop an intelligent energy routing system that integrates seamless access, efficient conversion, intelligent allocation, stable output and reliable communication of multiple energy sources. This invention is created to fill this key technical gap. Summary of the invention

The multi-energy access units are deployed in a dispersed manner, solar panels are spread all over the roofs, wind turbines stand around the community green space, and small hydropower facilities are embedded in the landscape water system. The high-precision solar tracking device of the solar energy collection interface operates in real time. In the early morning, with the first ray of sunlight, the device quickly and accurately locates and drives the solar panels to turn in two dimensions, capturing the strongest light with an accuracy of 0.1°. Compared with traditional fixed panels, the power generation capacity is significantly improved. On a sunny morning, it generates 30% more electricity than the surrounding fixed installation communities.

[0030] The energy standardization processing module converts the collected energy into stable direct current to charge the community energy storage station. The energy storage dispatching components are based on the residents' electricity usage habits. During the day when the electricity price is high, the discharge is controlled to slow down the power grid. At night, the low electricity price is charged and stored. The intelligent charge and discharge management system dynamically adjusts the current according to the battery status, maintaining the battery health like a baby. The life of lithium and lead-acid battery packs far exceeds expectations, and the self-discharge is almost negligible.

Before residents use electricity in the evening, it allocates energy storage and real-time energy in advance to ensure stable voltage. The energy output adaptation module outputs adaptive power for different households. Under the impact of air conditioning startup, it responds instantly to maintain voltage. The reactive power compensation unit keeps the power factor above 0.95, with excellent harmonic suppression, and the operation of electrical appliances is quiet and noiseless. The communication fusion gateway is networked with residents' smart meters and home appliance Internet of Things modules to provide real-time feedback on energy use. Residents can intuitively control it through mobile phone APPs and remotely adjust the energy-saving mode of home appliances. The community's energy utilization rate has jumped 20% compared to traditional methods, and the average monthly electricity bill expenditure has been saved by 25%.

On the cliffs by the sea, giant wind turbines stand tall. The multi-energy access unit connects to the wind energy with high resilience. The built-in regulation circuit smoothes out the intermittent wind power and collects energy efficiently. On the intertidal zone of the mudflat, hydropower turbines generate electricity with the power of tides, complementing wind energy. The adaptive interface of the access unit seamlessly integrates the energy of the two, and can steadily collect energy even if the fluctuation is large. Even in severe weather such as storm surges, energy access is uninterrupted.

[0035] After energy is standardized, it is stored in the energy storage and allocation components. Supercapacitors cope with instantaneous peak power consumption, lead-acid batteries provide continuous power supply, liquid cooling prevents the equipment from overheating under the scorching sun, and the active balancing circuit keeps the battery packs moving in unison, with minimal voltage differences. The intelligent core controller is like an island energy steward. Based on the wave and wind forecasts and the island's power consumption patterns, it carefully plans in the isolated island mode, increases energy storage reserves during the peak tourist season, and appropriately stores energy to maintain equipment operation during the off-season, with energy utilization efficiency exceeding 80%.

[0036] The energy output adapter module provides energy for various loads such as fishery processing workshops and homestays. The voltage is flexibly adjusted to the equipment adaptation value, and fault protection is provided instantly to prevent processing equipment from being damaged. The communication fusion gateway remotely exchanges data with the mainland power grid through satellite communication, draws on external dispatching experience to optimize itself, and edge computing locally pre-processes meteorological and electricity data to quickly decide on increasing or decreasing power generation or energy storage. The reliability of island power supply has soared from less than 70% to 95%. Clean energy has illuminated the new life of the island, diesel consumption has returned to zero, and the ecology has regained vitality.
