How to design a microgrid?

Appropriate sizing of microgrid components, that is, number and size of PV modules, batteries, DGs and associated power electronic devices determines the efficient and economic design of the microgrid. There are numerous sizing approaches available in the literature, which are subjective to the requirements of the microgrid operator.

How do you calculate power requirements for a microgrid?

The best way to estimate the future power requirements of the microgrid is to analyze or record data for the specific loads and introduce a contingency above the peak load.15 Other key considerations for understanding loads include power factor and system harmonics caused by nonlinear loads. See Appendix B for details on these considerations.

What is the design and optimal sizing of a microgrid?

The design and optimal sizing of a microgrid consist of determining the nominal capacity of generation systems, configuration, storage capacity, and the operational strategy to maximize reliability and minimize operational cost and pollutant emissions in the life cycle of the project, among other design objectives.

How is Tel calculated in a microgrid sizing with storage system?

Additionally, it is possible to use this criterion in a microgrid sizing with storage system, where TEL is only considered when the storage system charge is full and the excess of energy generation is lost. It is calculated as follows, where PG is the power available by the generation and storage system and PL is the power demand.

Why is microgrid sizing a complex problem?

Microgrids sizing is a complex problem due to the non-linearity and the complexity associated with the design criteria and the ECS/ESS modeling. The sizing problem statement requires not only gathering information such as energy potential and local demand but also defining design criteria based on objectives and implementation constraints.

What are the steps in microgrid sizing?

Step 1. Load assessment: Load assessment is one of the key steps in microgrid sizing. Thorough analysis of the load demand of the microgrid is essential for optimal selection of the microgrid generation mix and storage capacities.
