Introduction

Distributed energy systems have important practical significance and far-reaching strategic significance for building a clean, low-carbon, safe and efficient modern energy system.

GB/T 33757 "Energy Saving Rate of Distributed Cooling, Heating and Electricity Energy Systems" focuses on the statistical scope of energy saving rate of distributed cooling, heating and electricity energy systems. Range and calculation method.

GB/T 33757 aims to establish an energy-saving evaluation method for distributed cooling, heating and power energy systems, which is intended to consist of three parts.

— Part 1: Fossil energy driven systems. The purpose is to give the distributed cooling, heating and power systems driven by gas or liquid fossil energy.

Technical requirements, statistical scope and calculation method for energy saving rate of power source system.

— Part 2: Multi-energy complementary drive system. The purpose is to give gaseous or liquid fossil fuels, gaseous biomass fuels, hydrogen, Renewable energy generation (wind power, solar power, etc.), grid power (electricity from the public power grid), external industrial waste heat, solar thermal energy, etc.

Energy cascade utilization characteristics, multi-energy complementary utilization characteristics and renewable energy utilization characteristics of distributed cooling, heating and power energy systems driven by multi-energy complementary Analysis and evaluation methods for bioenergy utilization characteristics.

— Part 3: Non-fossil energy driven systems. The purpose is to provide a distributed cooling, heating and power energy system driven by pure renewable energy Technical requirements, statistical scope and calculation method of energy saving rate.
