[UC40] Phase Imbalance Correction Suggester

The Utility Problem

Phase balance in an electricity grid refers to the balance of the electrical power flowing through the three phases of the grid (A, B, and C). In a balanced grid, the power flowing through each phase is equal. However, when there is an imbalance, it means that the power flowing through one or more of the phases is different from the others.

An imbalance in the phase distribution can cause several problems such as:

• Reduced system efficiency and reliability: An imbalance in the phase distribution can cause an increase in system losses, reducing the overall efficiency and capacity of the grid that can lead to outages or safety breaches.
• Voltage fluctuations: An imbalance in the phase distribution can cause voltage fluctuations, which can affect the performance of equipment connected to the grid.
• Harmonics: An imbalance in the phase distribution can cause harmonic distortion, which can affect the power quality of the grid.

In the past, without the use of data analytics, correcting phase imbalance would have typically involved upgrading the power lines with a higher diameter conductor or a higher capacity transformer , which would have been a costly and time-consuming solution. With the use of data analytics, it is possible to identify which phase of the grid is more or less loaded and then redistribute the load across the three phases to ensure that the power flowing through each phase is equal.

By using data analytics, utilities can monitor the grid in real-time and identify potential issues before they become critical. This allows them to take proactive measures to correct phase imbalance, such as load balancing, instead of waiting for an imbalance to occur and then taking reactive measures.

By identifying which phase is more or less loaded, utilities can also identify opportunities to optimize the grid by switching some loads from a heavily loaded phase to a less loaded one. This can help to reduce the overall load on the grid, improve system efficiency, and prevent equipment damage. Additionally, switching some loads from heavily loaded phase to a less loaded one can be done with a relatively low investment cost compared to upgrading the conductors.
