Probabilistic Operation of Electric Power Systems Considering Environmental Constraint (Part 7)* -A Consideratioin for Line Security-
application/pdfA scheduling method is reported to satisfy the reliability limit and the environmental constraint when a line fault is regarded as probabilistic. The reliability limit is satisfied by changing the thermal output power to probabilistically achieve every line’s capacity. NO_x emission from thermal stations is limited as a typical environmental constraint. These constraints are economically achieved. The LaGrange’s method and the Kuhn-Tucker conditions are used to satisfy both the line capacity and the emission constraint. The LaGrange’s multipliers are decided by solving the simultaneous equations. An economical method of achieving the reliability limit is described using the probability of the line fault and the increase of the operating cost. Simulating the proposed method by a model system, the results are variously investigated. The proposed method is concretely confirmed to estimate the optimum operation which can economically satisfy the reliability limits and the emission constraints at various values. It is also shown that the proposed method can improve reliability by more than 16%.departmental bulletin pape

Multiplicity of steady states in kinetics of fructose-6-phosphate node (F6P-node).
<p>(<b>A</b>) Feedback activation of phosphofructokinase (PFK) by fructose-1,6-bisphosphate (F16BP) (<b>B</b>) Bistability in the kinetics of PFK due to feedback regulation by F16BP. The simulation was performed using only two enzymes PFK and aldolase (ALDO). F6P was varied and the steady state PFK flux was solved algebraically. Activation of PFK by F16BP was set at <b><i>K<sub>PFK,fbp</sub></i></b> = 0.65 mM. (<b>C</b>) Allosteric regulations in the F6P-node. (<b>D</b>) Modulation of bistability span by K/P ratio of PFKFB. The bifunctional enzyme PFKFB was integrated with PFK and ALDO to construct a three enzyme system. Simulations were performed at varying K/P value of PFKFB while keeping all other conditions the same as in (<b>B</b>).</p

Glycolytic behaviors observed in mammalian cells.
<p>Two types of glycolytic steady state kinetics were observed. These include steady state behavior with no multiplicity of states or those with multiplicity of states. The type of glycolytic isozymes expressed forms the basis for presence or absence of multiplicity of states in glycolysis activity. In case of non-proliferating cell, isozyme combination comprising of PFKP, PKM1 and PFKFB with K/P = 0.5 was used whereas in case of proliferating cell, isozyme combination including PFKM, PKM2 and PFKFB with K/P = 10 was employed.</p
