Abstract
To alleviate the shortcomings of large-scale grid connections for clean energy, which require stable thermoelectric units to provide backup services, a stable cooperative alliance among different energy types of power sellers must be established. Consequently, a reasonable method to distribute income is required, due to different contributions of each entity in the alliance. Therefore, this paper constructs a comprehensive correction algorithm for income distribution using an improved Shapely value method. We analyze the operating mode of the power seller, and establish the net income calculation model under both independent and alliance operations. We then establish an alliance operation optimization model that considers the constraints of unit output, as well as the balance between supply and demand, with the goal of maximizing income. Finally, an industrial park in a province of northern China is taken as an example to verify the model’s practicability and effectiveness. The results show that the power sales alliance can effectively promote clean energy consumption. The maximum reduction in thermal power generation and CO2 is 8510 MW and 684.515 tons, respectively. We apply the algorithm to income distribution and find that the thermal power seller’s income increased by ¥1,463,870, which enhances the stability of the alliance. Therefore, our income distributing optimization model guarantees the interests of each participant to the greatest extent, and serves as an important reference for income distribution.
Highlights
The distribution and the sales in China are being gradually liberalized under the continued implementation of the new electric power system reform and the policy of controlling the transmission, and opening the generation and sales sides
Different clean energy power sellers participate in power generation, crowding the available space for thermal power generation
Under the premise of satisfying its own power generation constraints, the thermoelectric units generate electricity according to the maximum load demand of each period of, and not exceeding 120% of the total demand of, the end-users
Summary
The distribution and the sales in China are being gradually liberalized under the continued implementation of the new electric power system reform and the policy of controlling the transmission, and opening the generation and sales sides. New types of power sellers have emerged, which effectively promotes the development of clean energy, including wind and photovoltaic [1]. Significant uncertainty and intermittency occur during renewable energy generation in a large-scale grid connection, leading to the reduction of grid stability and power quality, requiring stable thermal power units to provide backup services. This has led to the reduction of thermal power sellers’ enthusiasm to participate in power generation. Such work is necessary to establish a stable multi-energy hybrid power system (MEHPS) and guarantee the participation of every power seller
