Generator Rated-Power Control With Energy Storage Load Buffering
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Generators often operate inefficiently when the load power requirements do not match their rated power, leading to low fuel utilization and energy waste.
Innovation Solution
A power output method and apparatus for generators that includes determining the required power of an energy storage device, sending an inquiry to the device about switching to rated generating power, and adjusting power generation accordingly based on the device's consent or rejection signals to optimize fuel utilization.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of energy
If the generator operates at rated power, then fuel utilization is high, but the generator cannot meet load requirements when load power is less than or greater than rated power
Solution Approach 1:
The patent segments the power supply system into three components: generator, energy storage device, and load. The energy storage device acts as a buffer between the generator and load, allowing the generator to operate independently at optimal fuel efficiency while the energy storage device handles power fluctuations to match load requirements.
Solution Approach 2:
The energy storage device serves as an intermediary element between the generator and the load. It absorbs excess power when the generator produces more than the load needs and releases power when the load demands more than the generator produces, enabling the generator to maintain rated power operation for high fuel utilization.
2Adaptability or versatility
If the generator operates to meet variable load requirements, then load power needs are satisfied, but fuel utilization becomes low and energy is wasted
Solution Approach 1:
The energy storage device performs preliminary action by charging in advance when the generator produces excess power. This allows the generator to operate at rated power without worrying about immediate load demands, and the energy storage device is already charged to meet future load requirements.
Solution Approach 2:
The control unit continuously monitors the power requirements of the load and the state of the energy storage device, and adjusts the power flow accordingly. This feedback mechanism ensures the generator operates at optimal fuel efficiency while the energy storage device and control unit coordinate to meet varying load demands.
3Ease of operation
If the generator operates away from rated power, then load requirements are met, but the generator does not operate in the efficient operation power range
Solution Approach 1:
The energy storage device provides self-service by autonomously managing its own charging and discharging operations based on control unit instructions. This allows the generator to maintain constant rated power operation for high fuel conversion efficiency, while the energy storage device independently handles power balancing to meet load requirements.

AI summary
A power output method for a generator includes: when it is detected that an energy storage device is connected, obtaining required power of the energy storage device; sending a first inquiry instruction to the energy storage device, where the first inquiry instruction is used to inquire whether the energy storage device consents to switching of the required power to rated generating power, the rated generating power being corresponding power used when fuel utilization of a generator reaches preset fuel utilization; and when receiving a first consent signal fed back by the energy storage device, generating power using the rated generating power as target generating power, to supply power to the energy storage device; or when receiving a first rejection signal fed back by the energy storage device, generating power using the required power as target generating power, to supply power to the energy storage device.
