The effect of pH at different temperatures was studied on the forcevelocity characteristics of the sartorius muscle to estimate short-term compensation to temperature. The effect of thermal acclimation was also studied in order to estimate long-term compensation. A decrease in either pH or temperature reduced both tetanic tension and shortening velocity. There was a significant pH-temperature i...

Recently wide spread of power electronic equipment has caused an increase of the harmonic disturbances in the power systems. The nonlinear loads draw harmonic and reactive power components of current from ac mains. Current harmonics generated by nonlinear loads such as adjustable speed drives, static power supplies and UPS. Thus a perfect compensator is required to avoid the consequences due to...

Abstract. We consider a manager, who allocates some fixed total payment amount between N rational agents in order to maximize the aggregate production. The profit of i-th agent is the difference between the compensation (reward) obtained from the manager and the production cost. We compare (i) the normative compensation scheme, where the manager enforces the agents to follow an optimal cooperat...

This paper gives a new insight into the concept of load compensation using shunt active filter (SAF) under ideal and non-ideal source voltage conditions. A novel approach based on an improved instantaneous active and reactive current component method is proposed. The performance of the proposed control strategy has been compared with instantaneous reactive power theory, symmetrical component th...

Large perceptual class motor load is the main production equipment of metallurgical enterprise, although has taken independent secondary substation power supply mode, but due to the influence of the impact load, Often appears on the bus voltage drop and low power factor and harmonic big problems, , this article is based on SVC compensation control mechanism, the sectional control mode, the prin...

An integral plus resonant sliding mode direct power control (IRSMC DPC) strategy for voltage source converter high voltage direct current (VSC-HVDC) systems under unbalanced grid voltage conditions is proposed in this paper. Through detailed instantaneous power flow analysis, a generalized power compensation method, by which the ratio between the amplitude of active and reactive power ripples c...

Many definitions have been formulated to represent nonactive power for distorted voltages and currents in electronic and electrical systems. Unfortunately, no single universally suitable representation has been accepted as a prototype for this power component. This paper defines a nonactive power multivector from the most advanced multivectorial power theory based on the geometric algebra (GA)....

Three different conventional control strategies for extracting reference currents for shunt active power filters have been evaluated and their performance has been compared under various non linear loads. Comparison of the compensation ability of different control strategies based on THD and speed will be done and suggestions will be given for the selection of strategy to be used under differen...

In this paper, according to the lack of relevant studies based on reactive power compensation, the control method related to this subject has been investigated and applied to the Parallel Hybrid Active Power Filter (P-HAPF). Firstly, the dq base control algorithm is applied for harmonic compensation. Then, the reactive power compensation control which is supplied by active filter of hybrid acti...

The important task for the operation of autonomous micro grids, is to share the load demand using multiple distributed generation units. In this paper to realize satisfied power sharing without the communication between DG units, the voltage droop control and its different variations have been proposed. Generally, in a lowvoltage micro grids, due to the effects of feeder impedance, the droop co...
