| dc.title | An ADMM algorithm-based method for power trading considering carbon emission | en_US |
| dcterms.abstract | With the gradual progress of China's power industry, power system modelling and power market trading have become indispensable research contents. The aim of this thesis is to develop an electricity market trading method based on power flow model for distribution networks. The aim is to incentivise distribution grids and generators to achieve power balance at the lowest cost and to limit carbon emissions relatively. the thesis first builds a power flow model based on a nodal system and five types of constraints. The thesis presents the optimal power problem based on the cost function. Among them, the carbon emission constraint limits the carbon emission and total cost. Finally, an iterative algorithm based on the alternating direction method of multipliers is proposed to simulate the information exchange and power trading process between the distribution network and generators. The simulation results show that the model achieves the desired purpose with reliability and relevance. | en_US |
| dcterms.abstract | Specifically, an IEEE 18 node system is introduced as a basis at first. In the node model, four nodes are special nodes with generators. The other nodes are considered as a whole, i.e., the distribution grid. The thesis focuses on analysing the power transactions between the generators and the distribution grid. The thesis sets branch power constraints, voltage constraints, generator constraints for the node system to form a power flow model. The thesis also considers the current state of energy development by including a generator carbon emission value constraint and a carbon emission cost constraint. A cost function including generation cost, power loss and carbon emission cost is added on the basis of the power model. The power market trading model is thus realised. On this basis, the ideal value is calculated by the optimal power flow problem. The thesis modelled the power trading between nodes using the ADMM iterative algorithm. The algorithm is based on the ADMM algorithm. In the modelled electricity market, the roles include players and market rule makers. The players are further categorised into distribution network and generators. The algorithm sets penalty factors and updates the multipliers alternately and iteratively. The optimal solution is approximated by solving the OPF problem over and over again and the error is gradually reduced. In this way, the actual values of the model will be close to the ideal values, thus verifying the accuracy of the model. The results of the experimental simulation show that the model iterations produce actual values close to the theoretical values with a small error. As a result, the power trade between the distribution network and the generators at the four nodes is balanced. In addition, the cost function values and carbon emission values of the system are reduced and stabilised after trading. The model is accurate and realistic. | en_US |
