Advanced sizing tool and digital twin for power plants

Evaluate, size, and monitor solar PV and hybrid integrations with real-world controller dynamics

Overview

ECassessment

Description

ECassessment is ENcombi's proprietary software tool designed specifically to evaluate, size, and monitor your power systems. Operating seamlessly within the ENcombi ecosystem, it serves a dual purpose: acting as both a feasibility sizing tool for future projects and a digital twin for active, running power plants.

Feasibility Studies (Sizing) Simulate the addition of PV to an existing site with precision. By inputting energy requirements and environmental data, you can accurately assess whether a solar integration is viable and optimally size the system before any physical construction or capital expenditure begins.

Digital Twin (Monitoring) For power plants that are already operational and registered in ENcombi's ECcloud, ECassessment acts as a virtual replica. You can run simulations to compare the expected energy yield against the actual real-world performance of the site, making it incredibly easy to identify inefficiencies, curtailment losses, or hardware faults.

Realistic Controller Dynamics Unlike generic simulation tools, ECassessment factors in the exact control dynamics, algorithms, and settings of ENcombi's actual ECpv hardware controllers. This ensures that your simulations closely mirror real-world behavior and grid limitations.

Flexible Data Inputs & Integration Users can upload custom data sets using standard CSV files. If specific local weather data is missing, the tool calculates base solar irradiance and temperature using established meteorological models. Furthermore, it imports data sets directly from ECcloud, utilizing the same intuitive graphical data representation and reporting formats you are already used to.

ECassessment questions

How do I get access?

Contact sales@encombi.com for an ECassessment account. With it you can register as many assessment sites as you want, and grant any number of other ECassessment users access to view them free of charge.

What does my CSV file need to contain?

Date and time, and load in kW, are mandatory. Optional columns: genset online rated capacity, GHI, POA, ambient temperature, back-of-module temperature, genset and grid supply active (always as a pair), and PV generating capacity.

Several date and time formats and file separators are supported.

Can I use my PVsyst results?

Yes. The PV generating capacity can be taken from the dataset, so modelling from third-party tools like PVsyst carries over. Or ECassessment can calculate it.

What if I don't have irradiance or temperature data?

GHI can come from a clear-sky model, POA from GHI transposition, ambient temperature from historical weather data at the site, and back-of-module temperature from a model.

How long does an assessment take?

A few minutes, for a period of up to one year. The results are shown on the Executive, PV, Genset and Grid pages.

Can I make reports or export the data?

Yes. Reports can be tailored, created and downloaded manually, and data can be exported manually from the Admin page.
