Surplus Power Control System for Self-Generated Energy Facilities
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Surplus power generated by self-generated electrical power facilities like photovoltaic systems often goes wasted as existing systems lack an efficient method to consume this excess energy beyond selling it back to the grid or storing it in batteries.
Innovation Solution
A power control system that detects surplus power and directs it to chargeable electric devices or executes predetermined operations, predicting and optimizing the usage of surplus energy by selecting appropriate devices and operations based on stored information, ensuring efficient consumption without waste.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of energy
If surplus power is sold to electric power system or stored in storage battery, then power management is simplified, but surplus power is inevitably discarded when exceeding demand and storage capacity
Solution Approach 1:
The system enables self-generated power facilities to serve multiple purposes: power supply, surplus power consumption, and automatic control. The control unit automatically detects surplus power and directs it to appropriate electric devices without external intervention, making the system self-managing and reducing energy waste
Solution Approach 2:
The power control system integrates multiple functions into a single system: surplus power detection, power allocation decision-making, and control of multiple types of electric devices. This multi-functional approach allows the system to handle various power scenarios (selling, storing, consuming) through one unified control mechanism
2Productivity
If surplus power is directed to multiple electric devices, then power consumption efficiency increases, but control complexity increases
Solution Approach 1:
The control unit is pre-programmed with criteria for selecting electric devices to receive surplus power. It automatically evaluates available electric devices and their power consumption characteristics beforehand, enabling rapid decision-making when surplus power is detected without complex real-time calculations
Solution Approach 2:
The system incorporates feedback mechanisms where the control unit continuously monitors surplus power availability and adjusts power allocation to electric devices accordingly. This feedback loop ensures optimal power distribution while maintaining simple control through automatic adjustment based on real-time conditions

AI summary
A power control system controls electric devices so as to consume a power generated by a self-generated power facility using a natural energy, which is provided with a surplus power detection unit that detects the surplus portion of power generated by the self-generated power facility, and a device control unit that controls the operation of a plurality of electric devices. When the surplus power detection unit detects the surplus power, the device control unit controls one or more of a plurality of electric devices to perform predetermined operations so as to consume the surplus power.
