Advanced simultaneous activation algorithm

An electrosurgical system comprising:

• a first electrosurgical instrument;
• a second electrosurgical instrument;
• and
• an electrosurgical generator including:
• a power supply configured to output a DC waveform;
• a power converter coupled to the power supply and configured to generate a radio frequency waveform based on the DC waveform;
• an active terminal coupled to the power converter and configured to couple to the first electrosurgical instrument and the second electrosurgical instrument;
• at least one sensor coupled to the power converter and configured to sense at least one property of the radio frequency waveform;
• and
• a controller coupled to the power converter, the controller configured to:
• determine a first impedance associated with the first electrosurgical instrument and a second impedance associated with the second electrosurgical instrument based on the at least one property of the radio frequency waveform;
• and
• adjust power of the radio frequency waveform based on the first impedance and the second impedance.
