How to calculate wind energy potential in a microgrid?

Collecting meteorological data at the system possible locations is the first step of the microgrid design. Most commonly used approaches to quantify the energy potential are based on meteorological data and statistical analysis. Weibull probability function distribution is a widely used approach for wind energy potential assessment.

How to calculate PG and PL in a microgrid?

It is calculated as follows, where PG is the power available by the generation and storage system and PL is the power demand. The value should be only considered if PLOST is positive and according to the restriction previously exposed for microgrids with storage systems.

How can a microgrid meet its load demand?

The microgrid should be able to meet its load demand. To minimise the dependency of the microgrid on the electric distribution network, the energy generated from the renewable sources must equal the load demand of the system. Reliability is one of the key factor for microgrid sizing.
