Optimal Load Leveling Dispatch of CCHP Incorporating Photovoltaic and Storage
摘要
Abstract
The optimal dispatch of combined cooling,heating and power contributes to improving the utilization rate of energy. Also,it helps to mitigate the contradiction of power supply,promotes the integration of renewable energy and leveling peak load to a large extent.An optimal load leveling dispatch model of CCHP incorporating photovoltaic and storage is established. It aims at minimizing operation cost and peak-valley load difference.An economy coefficient is introduced to convert the multi-obj ective model to single-obj ective model.In view of the uncertainty regarding the prediction of load level and photovoltaic output,probability constraints are adopted to deal with the energy balance equation.Finally,it is tested on a CCHP system situated at Sino-Singapore Tianjin Eco-city to verify the validness and applicability.Optimal dispatch strategies in a summer day and in a winter day are given,respectively.Moreover,the impact of economy coefficient and confidential level on the obj ective is analyzed.关键词
