This paper proposes Second-Order Cone Programming (SOCP) model for Active Distribution Network Expansion Planning (ADNEP). The objective minimizes total investment and operation cost. Distributed Generation (DG) curtailment and load curtailment are used as the active management schemes to decrease the future operation risks of the planning. The expansion model allows alternatives to be considered...
The investment of a power transformer plays an important role in power equipment investment. Researchers have been focused on one-time cost of transformers while the future cost and benefit had been ignored. The life cycle cost (LCC) of a transformer was defined as the total cost through its whole life. Researches show that cost and effectiveness of the equipment are unity of opposites, and selecting...
At the present time the dedicated wired network is used widely to transfer power quality monitoring data. This transmission mode has some shortcomings, for example, the accessing terminals scope and the bandwidth resources are limited; the investment of the construction and maintenance is larger and the period is long. In view of the advantages of 3G technology, this paper proposed a 3G-based power...
Lightning transient characteristics of the grounding grid is the fundamental performance for lightning protection of the substation. The stability and safety of the 500-kV substation is of great importance to the safe operation of the power system. The characteristic of grounding grid is quite different from that at the power-frequency condition when subject to lightning impulse current. Using CDEGS...
North American Electric Reliability Corporation (NERC) and each regional reliability coordinator such as Western Electricity Coordinating Council (WECC) have created planning standards that define the scope of transmission planning study and the criteria of assessing stability. Transmission planning study identifies transmission upgrades to meet these criteria. In a transmission planning study, however,...
