What is a common consequence of not properly managing external load losses?

Not properly managing external load losses can lead to frequency instability within the power grid. When loads on the system are not accurately accounted for or managed, it can result in imbalances between supply and demand. These imbalances can cause fluctuations in system frequency, which is crucial for the stable operation of the electrical grid.

Frequency stability is essential for the proper functioning of power systems, as many generation units, especially synchronous generators, are designed to operate within a narrow frequency range. If there are unexpected external load losses, the system may experience sudden changes in frequency, potentially leading to cascading failures or even blackouts if not addressed promptly.

Effective management of external load losses helps to maintain a balance between generation and consumption, which is vital for preserving frequency stability and the overall reliability of the power system.
