This article discusses the specific features of such a product as reactive power. The degree power compensation both in domestic electric industry and most industrialized countries is clearly insufficient. possibilities available grids, at plants consumers electricity for coordinated regulation voltage levels are not fully used. main factors influencing formation market revealed. proposed based...

This paper presents a location-inventory-pricing model for designing the distribution network of a supply chain with price-sensitive demands and inventory-capacity constraints. The supply chain has market power and uses markup pricing. An efficient Lagrangian relaxation algorithm is proposed to solve the model. Our numerical study shows that by moderately increasing the number of possible value...

A new single-phase transformerless grid-connected PV inverter is presented in this paper. Investigations in transformerless grid-connected PV inverters indicate the existence of the leakage current is directly related to the variable common-mode voltage (CMV), which is presented in detail. On the other hand, in recent years it has become mandatory for the transformerless grid-connected PV inver...

This paper presents modeling, simulation and control of matrix converter (MC) for variable speed wind turbine (VSWT) system including permanent magnet synchronous generator (PMSG). At a given wind velocity, the power available from a wind turbine is a function of its shaft speed. In order to track maximum power, the MC adjusts the PMSG shaft speed.The proposed control system allowing independen...

We study utility indifference pricing of claim streams with intertemporal consumption and power (CRRA) utilities. We derive explicit formulas for the derivatives of the utility indifference price with respect to claims and wealth. The simple structure of these formulas is a reflection of surprising operator identities for the derivatives of the optimal consumption stream. For example, the parti...

With the aid of Taylor-based approximations, this paper presents results for pricing insurance contracts by using indifference pricing under general utility functions. We discuss the connection between the resulting “theoretical” indifference prices and the pricing rule-of-thumb that practitioners use: Best Estimate plus a “Market Value Margin”. Furthermore, we compare our approximations with k...
