Local Distribution Grid Optimization

Assignment: Calculation of optimal control of the substation for the next day (tariff switching and boiler blocking) using consumption prediction and photovoltaic production and subsequent comparison of its advantages with the currently used mass remote control method.

Our solution

We have created the new optimisation algorithm, which is based on weather forecasting, consumption prediction, PV production and the expected behaviour of consumers when switching tariffs in different situations.

Comparison of the use of mass remote control method and LODIS was analysed on real measured data. The key indicator was the “Losses” – the sum of squares of daily balance runs.

The result

Using the method of Losses comparison by searching for similar days proved significantly lower Losses rate in favor of our LODIS method, which was subsequently implemented.
