Actual Operation

With people attaching importance to sustainable development and reducing environmental pollution, distributed generation technology is attracting more and more and more attention due to its unique environmental protection and economy. However, distributed generation will change with natural conditions so that it can not output power constantly and steadily, and most DGs are connected to the power system at distribution network side, this will cause system stability problem. In order to fully play the role of distributed power and avoid the adverse effects of its existence, a power conversion sand energy storage system to effectively regulate the system stability of distributed generation connected to the grid is presented. MATLAB/Simulink is used as a simulation and study tool in this paper, a system model of distributed generation connected to the grid is built and combined with actual operation in different environments to conduct real-time simulation analysis, the simulation results show that the power conversion system can enhance system stability of distributed generation connected to the grid.

Micro grid may exert adequately distributed generation efficiency, and that wind Photovoltaic and Energy Storage is a key equipment in the micro grid. Aiming at the distributed generation existing intermittence and randomicity characteristic, the paper discussed the micro grid P/Q control method under the connection grid state and the micro grid U/F control method under the disconnection grid state. It also studied the distributed generation parameters variational law under the micro grid different run mode, and built the correlative mathematics model and tested by simulation. The results show: the control strategy ensured the mice grid running stably, and achieved the system anticipative design request, and offered theory foundation for the distributed generation extend application.

Effective Use

Thermal energy is necessary of many reasons. The most basic and most obvious includes food preparation and delivery of heat. Thermal energy storage is actually a temporary storage at high temperatures, respectively at low temperatures. It is an advanced technology, which can reduce environmental impact and it can facilitate more efficient and cleaner energy system. Nowadays, these systems have ability to retain thermal energy for a period of three months or more. The aim of design of these systems is to keep the thermal energy in summer period and to use it for heating in winter period. The role of such storage systems is to accumulate the heat, to balance temperature differences and to achieve the most effective use of the collected energy. This paper is focused on thermal analysis of system, which contains concrete tank. It is a system with water as a storage medium and the cooling of the water was monitored for 30 days.

The Impact

Based on new ship isolated power system, the models of power station, loads and hybrid energy storage system (HESS) are built. Fuzzy control theory is adopted to control different energy storage modules (ESM) coordinately, effectively level the fluctuation of loads and improve system stability. Simulations in Matlab/Simulink investigate the impact of different control filter parameters on compensation effect of HESS, and the impact of ESMs performance on HESS compensation.

Power Stability

The major drivers of the quest for optimal placement of flexible alternating current transmission system (FACTS) devices are the quest for smart grids and economic indicators. The demand for energy and power stability will continue much as the astronomic growth in industries and increase in global population remains. The aim of this paper is to deliver a panoramic view of the use of static synchronous compensator (STATCOM) in combination with energy storage system (ESS) in order to enhance power stability. In this paper, it was observed that application of ESS is an important factor in attaining power stability and mitigating the effect of dynamics associated with the power supply system. The miniaturization of batteries and adequate placement of STATCOMs will be a challenge much as new power system are built or existing ones are expanded. The future of ESS is towards the adoption of renewable energy sources as against batteries.

Locomotory Performance

Elastic energy storage mechanisms have been shown to improve locomotory performance and efficiency in many animals. In this paper we consider the role of elastic energy storage in jet locomotion of the squid, Loligo opalescens. The jet is powered by the contraction of circular muscles in the mantle. In addition, the mantle contains a collagen fibre based energy storage system (the mantle "spring") which captures some of the mechanical energy produced by the circular muscles and then releases this energy to power the refilling of the mantle cavity. The mantle spring is constructed so that it stores energy from the circular muscles only at a time in the jet cycle when, by virtue of the cylindrical geometry of the mantle, the circular muscles are unable, to apply their full mechanical output to the generation of hydrodynamic thrust. Thus the mantle spring increases the utilization of the circular muscles, and our analysis indicates that these muscles are used at virtually 100% of their potential through the entire jet. Presumably this increase in muscle utilization improves the locomotory performance of the squid. Other swimming animals, such as fish, may obtain similar benefits if elastic energy storage systems are constructed to capture energy at a time in the swimming cycle when muscles can not apply their full output to the generation of useful hydrodynamic forces.
