Energy storage units (ESU) can generate profit through providing multiple services. In order to maximize profit while meeting battery lifetime constraints, it is necessary to select the capacity and charge/discharge schedule of the battery. This paper proposes a methodology to calculate the necessary ESU battery capacity for a given power rating and the lifetime profitability of the ESU. Because the price of electricity is not known more than 24 hours in advance, forecasting is necessary when scheduling the ESU. The reduction in profitability of the ESU because of forecasting errors must be taken into account. The methodology applies ridge regression for price forecasting to overcome the problem of having many highly correlated inputs, which lead to poor performance of the forecaster. The methodology demonstrates the encouraging result that the profitability of an ESU is not highly sensitive to forecaster error, as the scheduler is insensitive to the types of errors introduced by the forecaster. This is because of the nature of the variance in electricity market price.

“…The low-pass filter (LPF) is usually used to decompose the low-frequency power and high-frequency power of the fluctuant loads [3,4], but the performance is not very well when it deals with the relatively medium-frequency loads. In addition, the intelligent algorithms are also used in hybrid energy storage system (HESS) [5,6,7], such as fuzzy control, artificial neural network, genetic algorithm. These intelligent algorithms are difficult to be realized by DSP because of their large amount of computation.…”

For a microgrid consisting of photovoltaic generators and hybrid energy storage systems (HESS) with the battery and supercapacitor (SC) banks, this paper presents a real time energy coordinated control method for both grid-connected and stand alone operation modes. In the proposed method, the low-frequency and high-frequency power of fluctuant loads are decomposed by the algorithm of Fast Fourier Transfer (FFT), and are sent to battery and supercapacitor banks, respectively, thus extending the service life of battery. To achieve the control objectives and realize the smooth transfer of different operation modes for the microgrid, a unified control strategy is designed for the inverter of battery, which enables it to operate at both islanding and grid-connected mode without detecting the operation mode of microgrid in advance. Simulation results show that the power of loads absorbed by battery is smooth, and the supercapacitor can respond to rapid fluctuation of the power of loads. With the unified control strategy, the power flows to grid can be controlled when the microgrid operates at grid-connected mode while the voltage and frequency on AC bus can be stabilized by the inverter of battery at the islanding mode.
