Embodiment

[0080] Such as Figure 1 to Figure 3 As shown in , the construction method of distributed energy storage investment planning model considering the full life cycle benefits includes the following steps:

[0081] 1) Based on the characteristics of distributed energy storage technology, the application value of distributed energy storage in different application scenarios is analyzed, and the application value of distributed energy storage in different application scenarios is obtained. The application scenarios include improving power supply reliability, Peak shaving and valley filling and investment delay; application value includes peak shaving, low storage and high generation arbitrage, environmental benefits, delay and reduction of grid congestion costs, and government subsidies;

[0082] Wherein, the objective function of investment planning in the application scenario of improving power supply reliability is specifically:

[0083]

[0084] where f LPSP is the load los...

Abstract

The invention discloses a distributed energy storage investment planning model construction method considering full life cycle benefits, which comprises the following steps: 1) obtaining the application value of distributed energy storage in different application scenes based on the technical characteristics of distributed energy storage; 2) analyzing and obtaining each cost of the distributed energy storage in the whole life cycle, 3) establishing a distributed energy storage whole life cycle benefit model by combining the application value of the distributed energy storage and each cost in the whole life cycle; 4) based on the distributed energy storage full life cycle benefit model, establishing a distributed energy storage investment planning model by taking the maximum benefit as a target; and 5) setting an objective function and a constraint condition of investment planning in different application scenes of the distributed energy storage to obtain the distributed energy storageinvestment planning method considering the full life cycle benefit. The distributed energy storage investment planning method is obtained on the basis of the application value of distributed energy storage in the same application scene and various costs in the whole life cycle.

Description

technical field [0001] The invention relates to the technical field of distributed energy storage, in particular to a method for constructing a distributed energy storage investment planning model considering full life cycle benefits. Background technique [0002] With the continuous advancement of supply-side reforms and the implementation of strategies such as energy Internet and "Internet +" smart energy, energy storage systems are more and more widely used in distribution networks. Energy storage has the characteristics of both "charge" and "source". When used as a load, it can eliminate the fluctuation of new energy; Power quality is an important means for the intelligent use of electricity by users and the friendly interaction between the source network and the load. With the implementation of the new electricity reform plan, the power grid will enter a new era of liberalization of electricity sales, the monopoly of the power grid will be broken, and different electri...
