Aiming to relieve the large amount of wind power curtailment during the heating period in the North China region, a thermal-electric decoupling (TED) approach is proposed to both bring down the constraint of forced power output of combined heat and power plants and increase the electric load level during valley load times that assist the power grid in consuming more wind power. The operating pr...

Wind energy offers a significant advantage such as no fuel costs and no emissions from generation. However, wind energy sources are variable and non-dispatchable. The utility grid is able to accommodate the variability of wind in smaller proportion along with the daily load. However, at high penetration levels, the variability can severely impact the utility reserve requirements and the cost as...

For solar photovoltaic (PV) and wind resources, the capacity factor is an important parameter describing the quality of the resource. As the share of variable renewable resources (such as PV and wind) on the electric system is increasing, so does curtailment (and the fraction of time when it cannot be avoided). At high levels of renewable generation, curtailments effectively change the practica...

BACKGROUND This paper examines whether individuals facing the threat of poverty are curtailing their consumption of various goods and services in a given order and, if among the expenditures that are cut back, there are also health expenditures. The location of individuals in this order of cutback is then used to derive the degree of their deprivation and the factors that affect the extent of t...

Under the constraints of fossil-fuel reserves depletion and climate change, expansion intermittent renewable generation creates a lot power integration issues which undeniably disturb overall system stability. Optimally planned, electricity storage systems are capable managing variability uncertainty energy sources, guaranteeing balance ensuring feasible economical operation. Here, outcomes der...

Ireland and other countries in the EU have binding targets for production of energy from renewable sources by 2020. Ireland’s Renewable Energy Action Plan aims to meet this target by producing 40% of electrical energy from renewable sources and most of this will come from wind power. In order to forecast the amount of wind power capacity required, it is necessary to forecast the amount of wind ...

Load shedding is generally regarded as the final option to evade voltage collapse and blackout following major overloads. The traditional method of load curtails random loads regardless their importance until system’s improved. Shedding without considering priority will lead power interruption in vital infrastructures. Hence, improve existing system protection scheme, development a more effecti...

In order to improve the economy and safety of multi-microgrids (MMGs) scheduling, this paper proposes a research on MMGs scheduling strategy that takes into account dynamic electricity prices based blockchain. We first introduce principle blockchain, analyze security combination blockchain design architecture process platform. Second, we set price model according total power supply demand MMGs,...

As the share of VRE (variable renewable energy) has grown rapidly, curtailment issues have arisen worldwide. This paper evaluates and compares situations in selected countries using an objective quantitative evaluation tool named “C-E map” (curtailment-energy map). The C-E map is a correlation between ratios that mean curtailed wind (or solar) energy per available shares solar). can draw histor...

Abstract Curtailment is a known phenomenon for wind turbine operators of both onshore and offshore generators (WTG). refers to the situation in which power output all WTG’s within windfarm forced below expected at occurring environmental conditions. A direct consequence curtailment loss production. In present contribution further consequences an farm (OWF) are studied from perspective support s...
