Case Study for Integrated Regional Energy Planning in Sino-Singapore Tianjin Eco-City

Regional integrated energy plan is considered for urban energy infrastructure utilization. Heating mode such as heating technology of central heating by waste heat recovery in power plant, geothermal heat, sewage water heat pump, ground source heat pump will be developed in Tianjin Eco-city. Electricity supplying mode such as urban power distribution network, solar power generation system, wind power generation system, biogas CHP and natural gas fired BCHP will be developed in eco-city. A medium pressure natural gas network will be developed with two gas pressure-regulating station in north and southern part of eco-city. Low energy consumption buildings have a low heating and air-conditioning energy consumption and electricity consumption. Based on the building energy simulation analysis, we put forward the indicator system of energy planning closely focus on the suitable energy demand. In this paper, the integrated energy planning with space and time characteristics is also presented and analyzed briefly.
