Research on the Combined Planning Mode of Distribution Network under the Condition of Incremental Distribution Opening-Up

The new electricity reform started in 2015 have issued a series of policy documents that the incremental distribution business is one of the core content. In this paper, a joint planning and operation model of distribution network is established under the condition of the deregulation of the distribution network. Three fictitious distribution networks are used to establish all possible combined planning and operation model. There are 5 possible programming models and the numerical example shows that the cost of the alliance including all the players is the smallest. The profit distribution model of cooperative game based on shapely value is also established in this paper, compared with the average distribution model finding that the Shapely allocation model can make the alliance stable that can optimize the allocation of resources also affect the long-term cooperation among stakeholders.

Study on Power Network Planning in Consideration of Demand Response of Aggregate Inverter Air-Conditioner Load

In this paper, a control model is set in which the AC running with lower frequency and fixed operating time while meeting users requirements. An aggregation control algorithm is designed achieving full advantage of the energy saving potential or optimal economy. The power network planning model is set with consideration of demand response incentive costs through genetic algorithm optimization. A numerical example demonstrates the effectiveness of the method.

Optimization and modeling of power supply capability in distribution system based on analyzing interconnections among main transformer

According to the basic thoughts of calculating power supply capability of distribution system, which is based on the interconnections among main transformers and the N-1 guideline, this paper put forward an improved optimization calculation model of maximum power supply capability considering constraints of main transformer overloading and tie-line capacity. The model described general process of the main transformer N-1 verification and the loads second transfer caused by the main transformers short-term overload. The model was solved using the linear optimization toolbox of MATLAB. On this basis, the paper defined three types of calculation modules for power supply capability and established the comprehensive analysis program. Finally the effectiveness of the method and model was verified through analyzing the power supply capability of a practical example.
