Multi-energy storage systems better coordinate the capacity of EES and TES, which improves the economy of RIES more effectively than other strategies. Table 7. Optimal ESS sites and capacities under different optimization strategies. 4.3. Operation results under the optimal configuration of multi-energy storage system
Multi-energy storage system employing different types of ESS helps to meet the complementary coordination between different types of energy storage, which is important in improving system flexibility, reliability and economy . Because of these advantages, the researches on hybrid energy storages of electricity and heat in RIES gradually rose.
The configuration of multi-energy storage system improves the ability of wind power to be consumed. By storing excess power from wind turbine, the utilization rate of wind power can reach 91.3%. The stored power is released during the peak demand, which reduces the power purchase of the grid.
A multi-energy storage optimal configuration model considering PDN and DHN were established to optimize the installation position and capacity of EES and TES to minimize the comprehensive cost of RIES. Three methods were compared by computation efficiency and optimum results.
In terms of energy storage forms, the combination of electric-thermal energy storage is commonly considered due to the good benefits provided in systems like combined heat and power units and solar systems [ , , , ].
A two-stage optimization model of multi-energy storage configuration is developed. The sites and capacities of hybrid energy storages in power and thermal networks are optimized. Three methods to determine the installation locations are compared. The economics performances at different configuration strategies are compared.
