Presence of distributed energy resources (DERs) in the case of proper planning can help to improve the technical and economic parameters of the system in distribution networks. In recent years, several algorithms and indices for optimal distributed generation planning with multiple objectives have been presented. In this paper, optimal placement and sizing of distributed generation sources with...

The paper presents the issues of a wind turbine-flywheel energy storage system (WT-FESS) operation under real conditions. Stochastic changes of wind energy in time cause significant fluctuations of the system output power and as a result have a negative impact on the quality of the generated electrical energy. In the author's opinion it is possible to reduce the aforementioned effects by using ...

The technology of demand side response introduced in distributed photovoltaic power supply was proposed in this paper. Analyzing the applicability of demand response which established by distributed photovoltaic, presenting system implementation architecture and basic technical requirements. Without considering the input of energy storage equipment, establishing the demand response model in the...

he systems analysis, test, and evaluation of strategic systems is a “preeminent technical leadership role” for ApL. This activity encompasses the planning, design, development, operation, and performance assessment of the Trident ii Weapon system, uniquely providing confidence-based performance assessments over untested trajectories. physicsbased scenario-independent statistical models are cumu...

The present paper is confined to the discussion of technical grade paraffin waxes as phase change material (PCM) for cool storage and the cool storage systems capital cost investment. The objective of this study is to determine the potential for using cool storage systems. The thermal properties of technical grade paraffin waxes as PCM are investigated, and static and dynamic cool storage proce...

the issue of unit commitment is one of the most important economic plans in power system. in modern and traditional power systems, in addition to being economical of the planning, the issue of security in unit operation is also of great importance. hence power system operation confronts units’ participation and input considering network security constrains. the issue of units’ participation is ...

In this research the simulation of an air independent Proton Exchange Membrane Fuel Cell (PEMFC) propulsion system was taken into consideration. The system consists of several parts including PEM fuel cell stack, metal hydride and liquid oxygen (LOX) tanks, and also pre-heaters of oxygen and hydrogen gases along with other heat exchangers, to ensure proper operation of system. The heat recovery...
