An efficient model and algorithm for the transmission-constrained multi-site combined heat and power system

The transmission-constrained multi-site CHP system can be operated cost-efficiently according to hourly demand forecast for heat and power by coordinating production and transmission activities among different sites. An efficient network power Simplex algorithm is developed to this end. Numerical experiments with realistic test data show that the algorithm is 7-360 (with average 30) times faster than a commercial LP code.
