“…This comparative study reveals that the price‐based secondary control is superior over the conventional one in terms of improvement in frequency control and increased earnings of the generators. Two‐area interconnected power system having thermal generators has been studied under ABT‐based AGC in India scenario . These generators having different control schemes and marginal costs operate to restore the nominal frequency and tie‐line power flow under ABT.…”

“…The Equation governs the profit made by the generator for unscheduled generation.

normalΔ P_{ri} = ((), normalΔ λ ((), s) - normalΔ C_{i} ((), s)) normalΔ P_{i},

where P ri is the profit made by the generator for unscheduled generation in INR, Δ C i is the deviation in marginal cost of the i th plant in INR/MWHr, Δ P i is the deviation in power generation in MW.…”

Summary The integration of renewable sources into conventional grid may result in the grid indiscipline in terms of frequency instability and tie‐line power fluctuations. Such situations are generally handled through automatic generation control using controller parameter tuning. In deregulated power system with several public and private participants, grid discipline is affected adversely due to the imbalance between contracted values and metered values of both generation and drawal of power. In India, the availability‐based tariff (ABT) is a great solution to handle imbalance at the interstate level. In renewable integration scenario, the charges for deviation of renewable power generators are not linked with frequency whereas for conventional generators, frequency‐linked pricing is adopted for unscheduled interchange (UI). This work is based on a three area interconnected power system with thermal, hydro, wind, and diesel/biomass generators. Frequency deviation is settled through primary control and ABT‐based secondary control in case of thermal, hydro, and diesel/biomass generators. As the availability of wind power is weather dependent and stochastic in nature, the wind generator is kept out of ABT‐based secondary control loop. Studies are done here to observe the effects on frequency and tie‐line power deviations when renewable generators are integrated or disconnected from the interconnected power system. With the presence of wind generator, the frequency plot introduces overshoots. All these studies are done for sudden perturbation in demand. The simulation work is performed in MATLAB/Simulink platform.
