Modern power system networks are often subjected to high stress due to meet the growing energy demand and operated close to their maximum stability limits. As a result, these networks are becoming less secure and always expecting the risk of voltage instability. Therefore, it has become inevitable to incorporate dynamic voltage stability analysis during planning of modern power system networks. As...
In this paper generalized definition of instantaneous power quantity in the multiphase system under balanced sinusoidal, unbalanced sinusoidal and unbalanced non-sinusoidal supply condition is discussed. In the area of Active Power Line Conditioners (APLC), shunt APLC is widely used in practice. Many reference current generation methods are proposed by different researchers, but most of them work...
This paper presents generalized definition of instantaneous power quantity in the multiphase system. This definition is presented without any co-ordinate transformation and is valid under sinusoidal and non-sinusoidal situations. In the area of Active Power Line Conditioners (APLC), shunt APLC is widely used in practice. This paper proposes a novel concept of decomposing the multiphase current vector...
A model has been presented to estimate the battery size in a Solar Home System with respect to the night time load and the panel size. Falling solar panel cost has opened up the possible options to reduce the battery size by increasing panel size. It has been shown that although the cost of the system increases by a small margin, an increased size of the solar panel enhances the overall energy output...
Different from conventional generation, the renewable resource, such as wind or solar generation, is energy limited and intermittent. It is challenging to identify the capacity credit of renewable generation. A new method has been proposed in this paper to determine the capacity credit for renewable resource in the framework of resource adequacy. An optimization model is developed first to calculate...
This paper provides an overview of probabilistic planning reserve margin studies at the California Independent System Operator. Currently, load serving entities in the State of California, with its retail load under the jurisdiction of the California Public Utility Commission, are required to procure reserve level at 15 - 17 percent. However, the requirement is deterministic in nature. The California...
Quantitative transmission system reliability is a prerequisite in transmission system planning and operating that supplying industrial and commercial customer loads. A utility industry traditionally has relied on a set of deterministic criteria such as the widely used N-1 criterion to guide transmission planning supplying all customer types, e. g., residential, agricultural, commercial, industrial...
