specific Embodiment

[0058] Based on the modified IEEE33 node power distribution system containing 3 retailers, such as image 3 As shown, to verify the proposed day-ahead energy harvesting model for retailers considering demand response resources. Assume that the retailer purchases distributed power at an agreed price of 0.35 yuan / kWh, sells electricity to users at a fixed price of 0.60 yuan / kWh, and the compensation price for reducing load during peak power consumption is 0.60 yuan / kWh; assuming nodes 2 to 17 Distributed power with a predicted output of 200kW is connected. The detailed parameters of the calculation example are shown in Table 1-Table 3. Given T sum =24h, and take hour as the period unit. According to the electricity price type DR reported by the users in the region, the retailers are classified and merged according to their parameter characteristics. For the convenience of explanation, the price-based DR of each node is divided into two groups. The first group of optimization...

Abstract

The present invention is a method for determining the day-ahead energy acquisition of electricity retailers considering demand response resources, which includes the following steps: 1) The retailer collects data from the smart meter at the user end, including the user's next day's electricity demand and demand response resources etc.; 2) The retailer predicts the DG output and electricity price in the wholesale market in the area; 3) The retailer uses the data grouping technology based on similarity to classify and merge the above data to reduce the scale of problem solving; 4) The retailer uses the data proposed in this paper The model is optimized and solved; 5) The retailer purchases electricity in the power day wholesale market according to the optimized result obtained, and uploads its own related plans to the DSO; 6) The retailer sends the instruction to the smart meter at the user end and accepts the DSO dispatch . The invention can effectively solve the problem of integrating demand response resources and provide a basis for formulating day-ahead energy acquisition schemes for retailers on the electricity retail side.

Description

technical field [0001] The invention belongs to the field of power system analysis, and in particular relates to a method for determining day-ahead energy acquisition of a power retailer considering demand response resources, and belongs to an innovative technology for determining a method for energy acquisition of a retailer in the power retail market. Background technique [0002] With the issuance of multiple heavyweight supporting documents for the new electricity reform, market entities and related businesses on the electricity sales side, bottom guarantee and universal service mechanisms, entry and exit mechanisms for electricity sales market entities, market-oriented transaction mechanisms, and electricity sales market credit systems Risk prevention mechanism, organization and implementation have been clarified. [0003] As an indispensable economic entity in the electricity market, retailers will play a key role in the future power distribution system. Retailers par...
