Original abstract
Energy Efficiency is aligned with the United Nation Sustainable Development Goal for ensuring access to affordable, reliable, sustainable and modern energy for all. Locally Integrated Energy Sector (LIES) concept is introduced for energy conservation between industrial, service and residential sectors. The LIES concept extended the Process Integration technique for energy recovery between multiple process plants through the utility system, known as Total Site Heat Integration (TSHI). However, the development of LIES techniques is divided into two main directions, which are heat and power energy integration. This paper introduces a sequential approach for integrating the heat and electricity system in a LIES. The optimization is done based on time frame, which Time Slices (TSLs) are identified based on drastic changes in heat and electricity supply and demand. The heat system is first analysed by TSHI techniques, which the heat excess and demand are determined. The excess and demand is then used for cogeneration opportunities estimation, which the backpressure and condensing turbine are used. The potential power generation estimated then included to analyse the electricity system using Power Pinch Analysis tools. The use of heat and power storage system are also included in the study, for assessing its impact on the LIES's energy efficiency. The study considered on- and off-grid power supply system to satisfy the power demand of the system. This proposed heat and power optimisation framework aims to select a system configuration with minimal energy cost.
