“…In [1], the authors aimed at deriving a practical way of determining the transfer limits through the PV curve considering the voltage, thermal limits and collapse between the sending and the receiving end. The results were that the transfer limits could be determined through the use of PV curves.…”

When planning HVDC connection into an area, many possible receiving end point could be available. To analyze all of them can be laborious and time-consuming. On the other hand, questions may arise as to why some were not considered, thus threatening the validity of the studies. In this paper, preliminary work on comparing loadflow studies to assess receiving end points is presented. Loadflow studies carried at various load levels are compared for a case of using negative load representations of HVDC with a case where a full HVDC model is implemented. Results show good agreement between the voltages obtained at various load levels, meaning that a simple negative load model representation of HVDC has a potential for use in a justifiable, preliminary screening various possible receiving end points in a transparent way.

“…Diversos outros trabalhos foram realizados para eliminar a singularidade da matriz Jacobiana (característica inerente do PMC) através da modificação do método de fluxo de carga convencional [64]- [66]. Essa modificação é necessária já que o método de fluxo de carga convencional diverge quando se está próximo do PMC, e essa divergência se deve ao fato de que a matriz Jacobiana é singular (determinante nulo) perto do PMC.…”

“…The study attempted to identify the best locations and the right amount of quick start resources needed to improve the operational efficiency and reliability in New England. The study utilizes the multi-area market simulation and reliability calculation features to determine the feasibility of using quick start resources to meet the reserve requirements [1][2][3][4][5][6][7]. The multi-area model accounts for the impact of inter-zonal transmission constraints and the intra-zonal transmission operation constraints under both normal and contingency conditions.…”

In Southwest Connecticut of the New England system, out-of-merit generation is often committed to provide operational reliability support due to transmission constraints and a lack of local quick-start resources. The resources related to these supplemental commitments are paid an additional amount that is over and above the energy market revenues. A one-year feasibility study was performed to investigate if the GridView model, an engineering and economic simulation program, could be used to identify the amount of generating or demand response resources that would be required to reduce out-of-merit generation commitment. The objective of this exercise was to develop the New England bulk power system model, reflecting all relevant transmission and generation system operating characteristics, and simulate the system to find out whether the program produces reasonable results for use in the regional resource planning effort. This feasibility study would also identify the amount of quick start capacity needed, under assumed competitive market conditions, to improve system operational reliability and market efficiency.
