“…Traditionally, the total amount of load shed is set based on experience and then distributed to each shedding step with certain algorithms. There are several distribution methods roughly in three categories: equal step-size schemes, incremental step-size schemes and decremental step-size schemes [19].…”

“…Small shifts in frequency do not degrade reliability or markets efficiency although large shifts can damage equipment, degrade load performance, and interfere with system protection schemes which may ultimately lead to system collapse." Bevrani et al [8] discuss control parameters and strategies in detail and stress that any degradation of electricity grid control system safety margins will result in frequent, unscheduled, widespread blackouts ("system collapse"). A recent German government report 2 highlights the likely catastrophic consequences resulting from any such event.…”

Academic discussion continues as to whether a fleet of grid-connected wind farms, widely dispersed across a single grid network, can provide a reliable electricity supply. One opinion is that wide geographical dispersion of wind farms provides sufficient smoothing of the intermittent and highly variable output of individual wind farms enabling the wind farm fleet to provide for base load demand. In an examination of the 5-minute time-averaged wind farm operational data for 21 large wind farms connected to the eastern Australian grid -geographically the largest, most widely dispersed, single interconnected grid in the world (AER, [1]) -this paper challenges that opinion. The findings also suggest that the connection of such a wind farm fleet, even one that is widely dispersed, poses significant security and reliability concerns to the eastern Australian grid. These findings have similar implications for the impact of wind farms on the security of electricity grids worldwide.

“…ESS can also provide ancillary services for example frequency control. Frequency control [6] is the only service discussed in this paper, as BESS companies supply spinning reserve for the power system. The aim of frequency control is to maintain the balance between demand and generation as shown in Fig.…”

This paper presents a series of operating schedules for Battery Energy Storage Companies (BESC) to provide peak shaving and spinning reserve services in the electricity markets under increasing wind penetration. As individual market participants, BESC can bid in ancillary services markets in an Independent System Operator (ISO) and contribute towards frequency and voltage support in the grid. Recent development in batteries technologies and availability of the day-ahead spot market prices would make BESC economically feasible. Profit maximization of BESC is achieved by determining the optimum capacity of Energy Storage Systems (ESS) required for meeting spinning reserve requirements as well as peak shaving. Historic spot market prices and frequency deviations from Australia Energy Market Operator (AEMO) are used for numerical simulations and the economic benefits of BESC is considered reflecting various aspects in Australia's National Electricity Markets (NEM).
