Demonstration of storage in the factory
Li-Ion battery installed in industrial zone
Duration of demonstration:
April 2016 - May 2020
The target is to analyse and enhance the distributed power generation, so that the dependence of the distribution network would be reduced.
A further step in this process is the introduction of electric storage batteries, managing their programming to reduce customer energy costs (using battery power during the most expensive tariff periods of the network) and also reducing the peak power of the energy bill, covering these with energy accumulated in batteries.
Exkal demonstration in STORY is based on a storage system with Ion- Lithium battery, adapting an existing Photovoltaic Facility of 112,70 kWp installed on the roof of the factory for instant self-consumption, into a storage facility, focus on several targets:
For the dimensioning of the storage system, we take as starting point for this demonstration:

"It's a great opportunity to show that the storage of energy is a reality that has already arrived, and will change our future."

Download from meter data of consumption & download from EMS MANAGER (meter) data of PV Generation
Main parts of the PV facility are:
The electrical cabinet that you see on the left hand is the inverter. It is the device that transforms direct energy into alternative current energy (DC to AC), thus making it possible to return energy to the general grid or to our internal grid, as it is in the case of self-consumption. I our case, this device is a model Ingecon Sun 100, manufactured by Ingeteam, of 100 kWn of power. On the right hand of the picture, you can see the electric board with all protections and control of the components, with DC components on the left hand and AC protections on the right hand.
In principle, the charge of the batteries would be made with the energy generated by the PV facility, but the power electronic Equipment, MM60 of 60 kVA / 54kW, will have the flexibility to make the charge of the batteries from the Electrical Grid, in the future.
In this particular project, the decision of charging or consuming energy of the batteries will be taken by an external control system designed based on parameters as DOD, cost of energy, consumption… The MM controls the flow of energy to have these data always monitored within the limits fit by the battery manufacturer not to be exceeded.
By controlling the active and reactive power Microgrid Manager MM60 may have the following functions:
Operation and supervision of the equipment is done remotely from MODBUS / TCP over Ethernet. Also it has an LCD display on the front that allows a basic monitoring of the equipment status.
