ENERGY MANAGEMENT SYSTEM
The DHYBRID Universal Power Platform (UPP) is a modular energy management and microgrid control solution. The DHYBRID UPP is manufacturer and technology independent and allows the implementation of different energy sources into one economic and sustainable hybrid power supply.
The modular approach of the DHYBRID UPP ensures economic viability of hybrid projects at any stage of the transition from conventional into 100% renewable energy generation.

Maximum Inverter Power Tracking (MIPT)
Microgrids with decentralized solar power plants can reduce diesel consumption significantly. However, they rarely work to their full potential because conventional energy management systems are unable to separately control the output of individual system parts.
With its patented Maximum Inverter Power Tracking (MIPT) technology, DHYBRID has developed a solution for dynamically optimizing the performance of solar plants in a microgrid. This reduces costs and increases the proportion of solar power in the energy supply without the need to invest in additional hardware.
The patented Maximum Inverter Power Tracking (MIPT) technology is an integral part of DHYBRID’s Universal Power Platform (UPP). UPP users do not need to invest in any additional hardware.
Using the MIPT software, the UPP controls each inverter individually by collecting data on consumption, feed-in power and other grid parameters several times per second so that it can identify the optimum settings.
The dynamic MIPT algorithm then distributes the maximum PV feed-in power across the connected inverters several times per second. This makes it easier to unlock the potential of plants that are functioning well, increasing the proportion of solar power in the microgrid.
Instead of controlling inverters individually, conventional microgrid energy management systems assign the same feed-in power to all devices.
For instance, all the inverters in a system may only be permitted to feed in a certain percentage of their nominal capacity. In such cases, PV plants within the microgrid which are generating high yields at a given time are treated the same as those that are not performing as well. The resulting power output losses are entirely avoidable and can have significant effects for microgrids in particular. This is because microgrids often include several PV plants that are all connected but may experience different degrees of shading, for instance.
This inflexible control system is particularly detrimental to performance if individual inverters fail. Defective inverters continue to have the same feed-in power assigned to them as all the other devices – despite the fact that they are no longer generating any energy. At the same time, fully operational plants that could compensate for this shortfall do not achieve their potential. MIPT, in contrast, detects outages automatically and can immediately offset them by engaging functioning plants.
