To maintain the interest of both energy supplier and demand side consumers in the electricity market, in this paper, we propose a Nash bargaining demand side management scheme that optimizes the demand loads to achieve a balanced interest distribution. We formulate the power distribution problem by the Nash bargaining framework, where the optimization objective, defined as social benefit, is product...
Facing the shortcomings of fuzzy set in fuzzy time series, a new data fuzzification method is presented by a kind of new fuzzy sets based on distance sense. Then, the reduction algorithm of fuzzy rules is given by the characteristic expansion method. Finally, through the forecasting of Alabama university enrollments, the results show that the proposed method is effective.
The paper deals with the motion of turning in place of a spherical robot for military reconnaissance and unknown environment exploration developed by us. The robot belongs to a nonholonomic and under-actuated system. The robot has 3 DOF and 2 inputs. The motion of turning in place can make a spherical robot with higher dexterity and environmental adaptability. The mathematical model of the turning...
Double-loop networks have been widely studied as architecture for local area networks. A double-loop digraph G(N; s1, s2) has N vertices 0, 1,..., N-l and 2N edges of two types: s1-edge: i??1 + s (mod N); i=0, 1,..., N-l, and s2-edge: i?? s + s2 (modN); i=0, 1,..., N-l, for some fixed steps 1?? s1<s2<N with gcd(N; s1, s2) = 1. Let D(N; s1, s2) be the diameter of G and let us define D(N) = min{...
In order to improve the performance of three phase voltage source PWM rectifiers, this paper presents a passivity-based control (PBC) strategy based on port-controlled Hamiltonian with dissipation (PCHD) model established from the rectifierspsila power circuit. With the model, a passivity-based controller for PWM rectifiers is designed by using Inter-connection and Damping Assignment passivity-based...
The general methods to design induction motor torque and speed controller are analyzed based on passivity-based control (PBC) methods. In order to accelerate the response of system, a constant damping is injected into passivity-based controller, which will lead to the speed fluctuation in the period of arriving stable state currently. To overcome the disadvantage a new control strategy is presented...
