Title: Review of energy system flexibility measures to enable high levels of variable renewable electricity Article Type: Review Article Keywords: energy system flexibility; DSM; energy storage; ancillary service; electricity market; smart grid Abstract: The paper reviews different approaches, technologies, and strategies to manage large-scale schemes of variable renewable electricity such as solar and wind power. We consider both supply and demand side measures. In addition to presenting energy system flexibility measures, their importance to renewable electricity is discussed. The flexibility measures available range from traditional ones such as grid extension or pumped hydro storage to more advanced strategies such as demand side management and demand side linked approaches, e.g. the use of electric vehicles for storing excess electricity, but also providing grid support services. Advanced batteries may offer new solutions in the future, though the high costs associated with batteries may restrict their use to smaller scale applications. Different "P2Y"-type of strategies, where P stands for surplus renewable power and Y for the energy form or energy service to which this excess in converted to, e.g. thermal energy, hydrogen, gas or mobility are receiving much attention as potential flexibility solutions, making use of the energy system as a whole. To "functionalize" or to assess the value of the various energy system flexibility measures, these need often be put into an electricity/energy market or utility service context. Summarizing, the outlook for managing large amounts of RE power in terms of options available seems to be promising.

As a new generation of direct current (DC) transmission technology, voltage sourced converter (VSC) based high voltage direct current (HVDC) has been widely developed and applied all over the world. China has also carried out a deep technical research and engineering application in this area, and at present, it has been stepped into a fast growing period. This paper gives a general review over China's VSC based HVDC in terms of engineering technology, application and future development. It comprehensively analyzes the technical difficulties and future development orientation on the aspects of the main configurations of VSC based HVDC system, topological structures of converters, control and protection technologies, flexible DC cables, converter valve tests, etc. It introduces the applicable fields and current status of China's VSC based HVDC projects, and analyzes the application trends of VSC based HVDC projects both in China and all over the world according to the development characteristics and demands of future power grids.

Abstract. In order to increase grid stability, there are some methods to reduce wind power fluctuation by using energy storage system (ESS). Operating time of ESS will determine its losses and the lifetime of batteries. From this point, this paper proposes a wind power smoothing control by calculating shortterm average value of wind power. In this case, the operation of ESS will be decided through detecting wind fluctuation rate during 60 seconds. It means that the ESS will not operate at small fluctuation of wind power which does not affect the grid stability. The effectiveness of proposed method will be verified by comparing the conventional method with the proposed method. The wind power data were measured by power quality analysis device from 15 MW wind farm in Jeju Island located in South of Korea peninsula. The simulation results are carried out by using Matlab program.
