Integrating high shares of renewable resources into the electricity system requires a more flexible demand, especially more load-shifting in residential households. In order to achieve that different technologies, especially smart meters with various feedback functions, are tested on the market. So far little is known about the effects of a combination of different smart home technologies, such...

Abstract: This paper presents a clock phase-shifting (CPS) energy balance control (EBC) method for cascaded half-bridge multilevel inverters in standalone solar photovoltaic (PV) systems. It is based on the conservation of energy in each cascaded unit. By shifting the phase of the clock pulse of each cascaded unit, a staircase-like output voltage is obtained. The CPS EBC not only regulates the ...

Transient stability of a power system is concerned with the system’s ability to remain in synchronism after the disturbance is cleared. Occurrence of a fault in a power system causes transients. The disturbances subjected to the system may be occurrence of fault, sudden change in load etc. This paper describes the improvement of transient stability with phase shift insertion by phase shifting t...

Electricity markets are systems for affecting the purchase and sale of electricity using supply and demand to set energy prices. Electricity can be traded in organized markets or by negotiating forward bilateral contracts. Demand response (DR) refers to participation by customers in electricity markets, seeing and responding to prices as they change over time. Customers may adopt several basic ...

Self reactanceXd in direct axis ’d’ and self reactanceXq in quadrature axis ’q’ influence the load characteristics of the permanent magnet machine. Their calculation methods are known. All calculations should be verified by measurements. Measurement with AC variable voltage and frequency source applied on stator winding is correct when eddy currents do not exist. Other methods evaluate the DC c...

A sliding strategy for load balancing is introduced. The strategy groups a certain number of adjacent nodes to perform a load balancing process. Upon the completion of a given period, the groups are to be rotated by shifting each group one position to the right, thus produces different groups. This strategy (sort of clustering) not only reduces the load balancing overheads, but also it could be...

This paper presents an optimized load management scheme for smart house facilitating a scoring rule operated reward based time dependent pricing mechanism. Smart houses are capable establishing two-way communications between consumers and energy providers and thus enabling a feedback-control loop using a time dependent pricing (TDP). The energy provider (EP) persuades the consumers to manage th...
