In light of the increasing number of participating members in the electricity market, the surge in the volume of electricity trading data and the rising demand for accuracy in electricity price forecasting, this paper proposes to construct a day-ahead electricity price forecasting method that considers multi-dimensional electricity price influencing factors. Firstly, the factors influencing the fo...Show More
Loss allocation plays a pivotal role in power transmission and distribution services as it is integral to the reconciliation process between generator-user settlements. The advent of distributed generation over the recent years has introduced bidirectional power flow along transformers and mainlines in conventional distribution networks, complicating the calculation of power losses and the rectifi...Show More
In this paper, a method for modeling and simulation of pneumatic transients of natural gas (NG) pipelines is proposed. The partial differential equations (PDEs) that describe the dynamics characteristics of the NG pipeline are converted to ordinary differential equations (ODEs) based on the difference approximation. Electrical analogies for pneumatic quantities are exploited. An equivalent circuit...Show More
Comprehensive energy system planning is the primary core issue of energy Internet construction. The existing energy station location, capacity determination and pipeline network layout planning of multi energy network are generally obtained by staged optimization or traditional intelligent optimization methods, resulting in the final result of non-optimal solution or local optimal solution; At the...Show More

Based on consumer psychology, a price-based demand response load model is established, which divides the load into two parts: the basic load and the response load. The basic load uses the distance space method to filter the load of the five characteristic quantities of the week, the holiday, the season, the date difference, and the weather from the historical load. The response load is modeled bas...Show More
Solid oxide fuel cell (SOFC) has received considerable attention nowadays. It can be used in the integrated energy system (IES) to provide both thermal power and electric power. For purposes of analysis of multi-physics phenomena, a SOFC model that considers electric, pneumatic, and thermal transients is developed in this paper. Electrical analogies for pneumatic and thermal quantities are exploit...Show More
