Currently there are tools for sizing photovoltaic systems, but also microgrids, available on the market, which take into account the proposed energy consumption, location of the site and the cost of the system. For microgrid projects, comparisons between communication mode, modules, converters and configurations of thousands of items in the database is no longer a difficult topic to address. Modules are available such as climate locations with street level resolution, 2D graphic and photographic arrangement of the roof and floor, 2D shading with digital import from surveys, etc.
We identify the best technical solution, suitable for each application and analyze the funding sources
The Smart Microgrid Controller
In order to verify the sizing methodology of microgrids, developed by SIS, in the second stage of the Smart µGC project, modeling and simulation with a tool already launched on the market, is an essential task of integrating microgrids in current energy applications. The PV * sol calculation program is a package designed for the study, sizing and analysis of data and the calculation of photovoltaic performance according to EN 15316-4-6.
Preliminary design – corresponds to the pre-sizing stage. With just a photo of the location where the photovoltaic panels will be mounted and some reference dimensions, it was possible to create a realistic representation of the property, as it would look with the installed panels, which provides a useful tool for the design process to decide where these modules should be best placed.
GENERAL DATA similar to those generated by the calculation according to the SIS methodology
- PV Generator Output: 127.26 kWp
- PV Generator Surface: 607.3 m²
- Number of PV Modules: 252
- Number of Inverters: 1
- PV Generator, 1. Module Area – Arbitrary Open Surface 01-Mounting Surface Southn
Project design – system simulations can be performed and compared according to the stage of defining the plan orientation and choosing different specific components of the system, but also determining the optimal load. String planes can be generated below the 3D dimension, while the cabling plane emerges. The software having the possibility to compare solutions with each other, in a tabulated interface of the parameters.
Superior advantages – Sizing methodology using the algorithm developed by SIS specialists
In addition, the results of the simulations presented by the SIS are focused on balancing power. An additional analysis should assess the state of operation of the GM at each time interval. It also involves identifying solutions that involve eliminating the extra burden. The simulation algorithm involves adjusting the power of a diesel generator, as a need to prioritize the power of the PV fleet and the balancing power of the blind system in such a way as to match the load. The sizing methodology using the algorithm developed by SIS specialists, offers superior advantages which include the analysis of variation of low battery power, especially during the rising and falling hours of photovoltaic generation, the conclusions being that a generator remains the main balancing entity. of this microgrid. Any adjustment of the power of the PV park means the loss of available energy.
