Two-way energy storage in office buildings and commercial parks

What kind of energy system does the park have?

At present, the park's hybrid energy system mainly consists of a photovoltaic power generation system, a ground-source heat pump system, an energy storage system, an ice storage cold system, a solar air-conditioning system, a solar water heating system, a thermal storage electric boiler system, and an electric power system (Fig. 7).

What are the different types of energy storage technologies?

Generally, there are two main potential storage technologies: electrical and thermal energy storages. Specifically, the electrical energy storage is able to provide operational flexibility among a building cluster, regulating the power to fit the buildings demand and enhancing the energy self-sufficiency.

Are building energy systems the fundamental design units of a societal energy system?

Consequently, treating building energy systems as the fundamental design units of a societal energy system, and performing performance analyses along with optimal configuration designs for hybrid energy systems at the building scale, are considered crucial strategies for addressing future renewable energy challenges .

What is thermal energy storage?

Thermal energy storage (TES) is one of several approaches to support the electrification and decarbonization of buildings. To electrify buildings eficiently, electrically powered heating, ventilation, and air conditioning (HVAC) equipment such as a heat pump can be integrated with TES systems.

Is space heating and cooling a viable energy storage solution?

Space heating and cooling account for up to 40% of the energy used in commercial buildings.1 Aligning this energy consumption with renewable energy generation through practical and viable energy storage solutions will be critical to achieving 100% clean energy by 2050.

How a hybrid energy system can improve the economic viability of building parks?

The park system has increased stability by 26.09%-56.70% and reduced economic costs by 24.85%-59.55%. The reasonable design of building hybrid energy system capacity configuration is crucial to ensuring the economic viability and applicability of decarbonized operational building parks.
