The pumped storage unit has good adjustment characteristics of a fast power response and convenient start stop, which provides support for the safe stable operation system. To this end, paper proposes fractional order PID (FOPID) optimization control method regional load frequency pumped-storage plants. Specifically, based on IEEE standards, established single-region model storage. Then, contro...

The converter is an important component of a wind turbine, and its control system has significant impact on the dynamic output characteristics turbine. For double-fed induction generator (DFIG) converter, parameter identification method proposed. In this paper, detailed model DFIG with built, trajectory sensitivity used to study observation points that are sensitive change parameters as quantit...

234 Abstract—Currently whole world is facing the problem of energy disaster. So to overcome this problem there is an urgent need to create awareness about optimal use of the energy, environmental and economic benefits and making a nation more energy-independent, for this one of the obvious thought is combined heat and power (CHP) or cogeneration. In this paper performance of TVAC_PSO is tested ...

This paper proposes an immune concentration based virus detection approach which utilizes a two-element concentration vector to construct the feature. In this approach, ‘self’ and ‘nonself’ concentrations are extracted through ‘self’ and ‘nonself’ detector libraries, respectively, to form a vector with two elements of concentrations for characterizing the program efficiently and fast. Several c...

To improve particle swarm optimization (PSO) computing performance, the centroid of particle swarm is firstly introduced in standard PSO model to enhance interparticle cooperation and information sharing capabilities, then combining randomness and ergodicity of the strong chaotic motion and fast convergence of the simplex method, a novel particle swarm optimization algorithm with adaptive space...

Electronic mail (email) enjoys wide acceptance among the general public1,2 but has more limited acceptance among physicians.3 A 2005 survey found that 46% of Canadian physicians used email to communicate with colleagues for clinical purposes.4 Although email can be extremely useful, physicians need to appreciate the potential hazards of using email in clinical practice.5 The College of Physicia...

The concept of Cyber-Physical Society (CPSo) expands the concept of Cyber-Physical Systems (CPS) by including aspects related to knowledge, culture and society. Embedding computation in the control of our fast evolving society means mainly to trigger self-organizing mechanisms at any level in our complex world. The way democracy is exercised must benefit explicitly from the tremendous developme...

In this paper, the Unified Power Flow Controller (UPFC) is enhanced with a Chaotic Particle Swarm Optimization (CPSO) Damping Controller in order to mitigate the Low Frequency Oscillations (LFO) in a Single Machine Infinite Bus (SMIB) power system. The designed damping controller is an optimized lead-lag controller, which extracts the speed deviation of the generator rotor and generates the out...

A fault diagnosis method for sensor fault based on ensemble empirical mode decomposition (EEMD) energy entropy and optimized structural parameters least squares support vector machine (LSSVM) is put forward in this paper. Firstly, the original output fault signals are pretreatment with EEMD, and then the EEMD energy entropy is extracted as the fault feature vector. Then the radial basis functio...
