摘要

基于冷热电负荷组合和满足制冷负荷的方式，将包含吸收式制冷和电动制冷的冷热电联产系统的运行空间分成4种状态，每种状态下有3种运行策略。基于冷热电联产系统的运行优化模型，采用库恩-塔克(KT)条件获得了4种状态下各个运行策略为最优策略的条件。基于最优运行策略的条件分析，一种新的同时满足冷热电负荷的运行策略被证明具有最优性质。分析表明，最优策略与负荷的特征、购电价格、天然气价格、冷热电联产系统的效率等因素有关，提出的最优策略判别式可基于这些因素得出最优的运行策略。基于冷热电负荷组合和实际系统的计算结果验证了所述最优运行策略条件的正确性。

Abstract

Based on the cooling

heating and power load profile and the ways to meet the cooling load

the operation space of the combined cooling

heating and power(CCHP)is divided into four states

each with three operational strategies. The condition as an optimal operation strategy is obtained by the KT condition of the optimal operation model. A new operational strategy that meets the cooling heating and power load only by primal generation and heat recovery system is proved to be an optimal operation strategy. It is shown that the optimal operation strategy of CCHP is related to the electricity price

gas price

load composed of cooling

heating and power

and the efficiency of CCHP. The optimal strategy can be obtained by the proposed discriminator by considering those factors. The calculation results based on cooling

heating and power load and the actual system show the correctness of the conditions for the proposed optimal operation strategy.
