What is a Microgrid

DOE*: Definition of a MicroGrid DOE*: Definition of a MicroGrid

““A group of A group of interconnected loads and Distributed Energy Resources (DEinterconnected loads and Distributed Energy Resources (DE R)R) with clearly defined electricalwith clearly defined electrical boundaries that acts as a single controllable entity with respect to the grid [and can] connect and disconnect boundaries that acts as a single controllable entity with respect to the grid [and can] connect and disconnect from the grid to enable it to operate in bo

Situation Today

Remote diesel power generation in the middle of nowhere e.g. Mine in Namibian Dessert

Diesel generators running 24/7 Switchgear Room

Game changer – PV is getting cheaper

Business case:

Invest in adding PV Power to existing or new diesel power generation sites,

to reduce OPEX and save fuel. ROI within 4-5 years!

PV Hybrid basics



PV Inverter is not grid forming!



PV Inverter cannot operated in island mode



PV Inverter used for grid tied system (ON Grid)



In Diesel PV Hybrid system the diesel genset is the grid



Make sure a PV Inverter is used which is suitable for hybrid

operation (no shut downs if U and f is out of range) which could

happen in a diesel island operated grid.



PV Inverter must have remote control possiblity to adjust kW

Diesel PV basics

Diesel gensets doing loadsharing and sequenzing according to load requirements Load 500kW 500kW 500kW 225kW PV Power =15% of 1500kW ~

_

Up to ~15% PV can be added as negative load to the gensets No control of PV Inverter required!

Diesel PV basics – What happen when more PV is added?

Diesel gensets doing loadsharing and sequenzing according to load requirements Load

500kW 500kW 500kW

500 kW PV Power =33 % of 1500kW

~

_

PV Power is pushing Diesel gensets into Reverse Power! Shut down of the Diesel gensets!

DER CONTROL is collecting actual kW information from each source.

In case of to low diesel load and to high PV Penetration DER CONTROL will decrease kW at PV Inverter

ON/OFF Grid Application

- Used in bad grid application

- Where it is allowed to export PV power

- Where it is forbidden to interconnect gensets - If grid is down, gensets and PV operated in Hybrid

mode

- LS5 used as a kW transducer and as breaker open/close indicator
