Real-Time PV Grid Capacity Sensor

Microgrids are localized grid systems that can function independent of a traditional grid. Ensuring their efficiency and efficacy depends on accurately predicting their capacity. An inaccurate capacity reading can disrupt microgrid-dependent operations and lead to inefficiencies in power usage, adding to operational complications. Current approaches for estimating microgrid capacity tend to rely heavily on energy storage device readings. However, these methods often overlook the fluctuating nature of power-consumption patterns, leading to imprecise results. An effective solution is needed to minimize the likelihood of inaccurate readings that can adversely impact effective power distribution and overall electricity consumption.

Technology Description

This novel methodology for determining the capacity of a microgrid entails applying a current test load to the microgrid and measuring the current flowing through an energy storage device integrated with the microgrid. The test load helps to ascertain the device's charging status. Further, the method incorporates figuring the capacity if the measured current indicates that the energy storage device is discharging. This capacity is the current load applied to the microgrid through previously activated power outlets and a test load prior to the current test load. The technology is differentiated by its unique approach to microgrid capacity determination. Unlike traditional methods, this approach systematically combines load application, current measurement, and analysis of charging status to accurately establish the microgrid's capacity. This methodology can help manage microgrids more effectively by adjusting power distribution and usage on the basis of the determined capacity.
