differential equation (ODE) in that a DAE is not completely solvable for the derivatives of all components of the function x.Every solution of the second half g of the equation defines a unique direction for x via the first half f of the equations, while the direction for y is arbitrary....
For each test case, please output x, y in one line. If there is a solution, because x <= y, the solution is unique. If there is no solution, please output -1, -1 1. 2. 3. 4. 示例1 输入 复制 10 4 4 5 6 10 10 10 25 20000 100000000 0 5 3 6 220 284 0 1 1000000000 ...

power flow decompositionThe goal of this work is to calculate partial phase shift flows for each phase shifting transformer (PST). In opposite to the approach using phase shift distribution factors (PSDF)- and the Newton-Raphson power flow calculation with PSTs modelled as admittance, a new ...
This paper reports results of extending the iTesla Modelica Power System Library with the implementation of new Modelica models for power electronic-based FACTS (Flexible AC Transmission System) to be used in phasor time-domain simulations. To show the applicability of Modelica for modeling FACTS dev...
