Problems solved by technology

In addition, there are currently few articles that consider the use of non-cooperative game ideas to optimize decision-making on aggregator load reduction bids
[0004] It can be seen that there is currently no two-tier scheduling optimization of various types of household loads by using non-cooperative game ideas.

Embodiment Construction

[0044] The technical solution of the present invention will be further introduced below in conjunction with the accompanying drawings and specific embodiments.

[0045] The two-tier dispatching scenario of residents’ load involved in this specific implementation is as follows: figure 1 As shown, on the upper market side, the dispatching department of the power company will predict the load level of the next day based on the historical load data, determine the peak load period and the market price information on load reduction in each period, and notify the relevant information to all aggregator. After receiving the load and price information, the aggregator takes the maximum flexible load reported by all participating load scheduling users in the jurisdiction as a constraint condition, and conducts non-cooperative game bidding with other aggregators to determine the scheduling of each aggregator in each time period plan. On the lower user side, users in the aggregator’s juri...

Abstract

The invention discloses a non-cooperative game-based residential load two-level scheduling optimization method, which comprises the following steps: S1: constructing a load aggregator non-cooperative game model for an upper market side; S2: constructing a resident load real-time scheduling model for a lower user side; S3: by solving the non-cooperative game model and the real-time scheduling model, allowing the load aggregator to obtain the optimal load reduction bid amount and the most reasonable load scheduling strategy. The non-cooperative game idea is introduced into the demand response, and a load aggregator profit function is converted into the non-cooperative game model according to the non-cooperative game idea; the aggregator obtains the optimal load reduction bid amount at the peak load period by solving the non-cooperative game module, i.e., finding a Nash equilibrium solution; the optimal real-time scheduling of user load is carried out based on the bid amount according to three types of load electricity physical characteristics of users, so that the profit of the aggregator is maximized under the condition of ensuring the comfort degree of the users.

Description

technical field [0001] The invention relates to an optimization method for double-layer dispatching of resident loads, in particular to a non-cooperative game-based optimization method for double-layer dispatching of resident loads. Background technique [0002] The demand side is an important part of the smart grid, and the regulatory role of demand-side resources in the power grid has gradually emerged, and two-way interaction with the power grid in the form of demand response. Among the demand-side resources, the electricity consumption of residential users accounts for 36.6% of the total electricity consumption of the society, but the load elasticity level of individual users is low, which cannot reach the minimum level of participation in demand response. Therefore, load aggregators can aggregate user flexible load resources to achieve the lowest level of participation in demand response, thereby participating in grid dispatch. As an emerging independent electricity sa...
