摘要

像热电联产(CHP)这样的热电联产系统越来越受欢迎,因为它可以再利用余热来产生可用的热能,也增加了系统的整体灵活性,增加了热电系统之间的协调。使用热泵(HP)有助于实现显著的系统效益,例如HP可以有效地为消费者提供热能,从而降低热电联产(CHP)机组集中供热的运营成本。本文开发了一个框架来评估将HP集成到具有储能系统(ESS)的热电联产系统中的经济效益。基于IEEE 24总线系统的案例研究表明,通过投资于HP和ESS,热电联产系统的运营成本可以在电力和供暖部门有效地降低。本文考虑了三种情况。以具有热电联产、热泵和储能系统(ESS)的ieee24总线系统为基础,进行了直流最优潮流(DCOPF)计算。情况1排除ESS,情况2排除CHP。计算每个案例的区位边际价格(LMPs),然后对结果进行比较。此外,还观察了对热价格的影响。

Optimal Dispatch of CHP in Network with Heat Pump and Electric Storage
Cogeneration system like combined heat and power (CHP) is gaining popularity because it can reuse the waste heat to produce useable thermal energy, also it increases the overall flexibility of the system and increases coordination between heat and electricity systems. Using a heat pump (HP) helps achieve significant system benefits such as HP can efficiently provide heat energy for consumers, which reduces the operational costs of central heat supply from combined heat and power (CHP) units. In this paper, a framework is developed to evaluate the economic benefits of integrating HP into a CHP system with Energy Storage System (ESS). Case studies based on the IEEE 24-bus system demonstrate that by investing in HP and ESS, the operational costs of CHP systems can be effectively reduced in both the electric and heating sectors. In this paper three cases are considered. DC Optimal Power Flow (DCOPF) on IEEE 24 bus system having CHP, Heat Pump and Energy Storage System (ESS) is performed and it is considered as base case. Case I is considered by excluding ESS and Case II is considered by excluding CHP. Locational Marginal Prices (LMPs) are calculated for each case and the results are then compared. Also, the impacts on Heat price are observed.
