Market-Oriented Consumption Model Based on the Joint Tracking of Renewable Energy Generation Curve of “Shared Energy Storage & Demand Side Resources”

Abstract

The fluctuation of renewable energy output brings many challenges to the operation of power system, which also indirectly affects the consumption of renewable energy. This paper proposes a market-oriented consumption model based on “shared energy storage and demand side resources” to track renewable energy generation curve. This paper combs the benefits of each party when participating in the transaction, and gives an example to illustrate how the parties benefit from the transaction. The market transaction mode proposed in this paper can enhance the user’s adaptability to renewable energy output by using energy storage equipment; additionally, it can avoid the risk of building energy storage facilities due to participation in the transaction. This provides a feasible idea for further improving the capacity of renewable energy consumption in China.

Battery energy scheduling and benefit distribution models under shared energy storage: A mini review

“…With the application of shared energy storage in various scenarios and countries, shared energy storage to absorb renewable energy (Liu et al, 2021;Tercan et al, 2022), shared energy storage auxiliary services (Ma et al, 2022;Nagpal et al, 2022), and evaluation systems (Qiu et al, 2021;Shi et al, 2021) are all hot topics in research. However, we believe that the core issue is how to ensure the efficiency of resource allocation and the fairness of income distribution under the sharing economy.…”

“…The multi-stage problems consider energy storage capacity installation along with energy allocation and dispatch (Wu et al, 2021). Common multi-stage problems can be summarized in a twolayer model, where the upper layer considers the capacity installation in the grid and the lower layer optimizes the allocation of energy storage (Long et al, 2018;Cui et al, 2019;Li et al, 2021;Wu et al, 2021;Ma et al, 2022;Wang et al, 2022), and such problems are characterized by trade-offs between the upper and lower layer models choices, where higher installation costs reduce the dispatch cost, and conversely, an insufficient initial capacity installation makes the allocation cost increase. The disadvantage of the model is that it treats the shared energy storage problem exclusively as an energy problem and ignores its economic properties.…”

“…The disadvantage of the model is that it treats the shared energy storage problem exclusively as an energy problem and ignores its economic properties. Another multi-stage problem regarding shared energy storage is to study the minimization of energy storage cost in the first stage and benefits allocation in the second stage (Li et al, 2021;Shuai et al, 2021;Li et al, 2022b), and such model omits the energy deployment process and focuses only on the total energy use efficiency and the individual benefit allocation problem. The drawback is that the model results are only suitable for macroscopic analysis and not for specific applications because the details of dispatching are ignored.…”

“…Cooperative games use negotiations and alliances to achieve efficient benefit distribution at a lower total cost. Common mechanisms are the Shapley value allocation approach (Li et al, 2021;Gao et al, 2022;Jiang et al, 2022), and the Nash bargaining method (Cui et al, 2021b;Huang et al, 2022;Liu et al, 2022). The Shapley method values the marginal contribution of the individual, whereas Nash bargaining focuses on maximizing individual returns.…”

“…Jiang et al (2022) proposed a cooperative game model under the framework of energy cells, using the Shapley value to allocate benefits and costs. Li et al (2021) considered the Shapley values and individual differences to design the optimal allocation. The advantage of this method is fairness but the drawback is that the alliance is unstable and the participants may leave the large alliance and form a small alliance.…”
