Optimal Parameter Selection of Gas-Fired Units for Distributed Cogeneration in an Industrial Town Based on an Industrial Service Company Perspective

摘要

Industrial service companies incentivize the investors to install distributed generation, to improve network environmental performance and efficiency. This paper proposes an approximated dynamic approach for optimal parameter selection of gas-fired units to supply electrical and thermal loads in an industrial town considering industrial service company perspective. A cost-benefit analysis with considering gas units, heat recovery system and distribution network constrains is performed for Optimal sizing, placement and timing for CHP installation. The main objective of the model is to minimize the company's operating costs in five years. Two aspects are considered in problem formulation: priority of the heat generation r electricity generation. Also, a multi objective genetic algorithm is used to solve the problem. Moreover, the PIKO feeder, one of the MANA VI substation feeders in TEHRAN, is employed as the study system. The simulation results show a significant decrease in the industrial service company operating costs, especially loss costs in five years.
