Achieving supply demand balance in power systems requires controllable energy storage. The primary sources of controllable storage are the fuel stockpiles at generators (i.e. gas, coal, water, etc.). There is increasing interest in alternative forms of storage due to factors such as the continuing increase in intermittent energy generation sources, concerns with increasing network costs and demand...
Since 2004 changes in the regulatory framework of the Chilean public and electricity sectors have been taken place (19940 law in March 2004). Transparency rules must be following by the market agents in pricing procedures of the electricity market. Consequently, technical, economical, and reliability data of the Chilean power system are available for simulation and optimization purposes. The Chilean...
This paper presents generator maintenance scheduling (GMS) and economic dispatch (ED) of the Indonesian power system based on minimization of an economic cost function for the economical and reliable operation of a power system, while satisfying crew/manpower, maintenance window, load demand, generation limits and spinning reserve constraints. Differential evolution (DE), an evolutionary computation...
Reserve plays an important role in maintaining power system reliability and security. It has practical significance and applicable value taking interruptible load for one kind of reserves to ensure power system reliability and optimize the resource in the electricity market environment. At present, interruptible load has participated in some reserve markets together with generator, but the existing...
This article deals with the challenges in reliability, security, efficiency, and resilience of energy infrastructure for a smart self-healing electric power grid. The electricity grid faces three looming challenges: its organization, its technical ability to meet 25 year and 50 year electricity needs, and its ability to increase its efficiency without diminishing its reliability and security. These...
