“…Similar power grid operation status data and monitoring data, energy management data and power consumption data are unstructured data. The dispatching convergence error is large, which affects the dispatching optimization effect [5]. In this paper, the integrated data of the power grid dispatching is classified without considering the structured data, as shown in Figure 1 below.…”

In view of the high cost of integrated energy dispatching in the power grid, which affects the economic benefits of power enterprises, an optimization method of integrated energy dispatching in the power grid based on multivariate big data is designed. The method comprises the following steps of: firstly, extract integrated data characteristics of power grid dispatching, and integrate power grid energy dispatching data; secondly, process the power grid energy dispatching data by using multiple big data, and reduce a dispatching convergence error; and finally, construct a power grid integrated energy dispatching optimization model, improve the net profit of power grid dispatching, and further realize the optimal dispatching of the demand of a supply side and a demand side of a power grid. By the way of comparative experiments, it is verified that the net profit of this method is higher. The economic benefit is higher, and it can be applied to real life.

The reduction in inertia increases frequency oscillations of the system, as discussed in [7][8][9][10][11][12][13][14].

The dependence of distributed generations (DGs) on climate conditions and fluctuating load demands are the challenges for the implementation of battery energy storage systems (BESSs) in islanded microgrids. BESS participation in system frequency regulation becomes one of the solutions to those challenges. Frequency regulation by BESS can be realized by applying the load-frequency control (LFC) in BESS. However, this participation clearly poses problems for the battery state of charge (SOC), as the battery is often overcharged or undercharged. In this paper, a control that maintains SOC at a certain level is introduced. This control strategy focuses on the battery operation function, which is determined from five control scenarios. All scenarios are achieved by applying the droop reference shifting method in the LFC to allow battery operation change. Control verification is carried out on an islanded microgrid system that experiences load demand changes and photovoltaic (PV) output power changes. The test results show that the SOC is maintained at 45–75% by applying load and PV power variations. The results correspond to the predetermined criteria control.

The application of battery energy storage (BES) in microgrid systems has attracted much attention in recent years. It is because the BES is able to store excess power and discharge its power when needed. In islanded microgrid systems, BES is starting to be considered as a unit that can regulate the system frequency. The control used in the BES to display frequency regulation performance is called load-frequency control (LFC). However, this participation resulted in the large size of the battery and high expansion planning cost. In this paper, an advanced LFC control that has frequency limitation compared to traditional LFC is proposed. The proposed control implies droop control as the base and has frequency limitations. Compared to the traditional LFC, the proposed control can reduce the system expansion planning costs. A performance simulation was done to validate battery performance. The results of the numerical simulation showed that the proposed control participated in reducing the operation cost. It directly led to a reduction in the expansion planning cost. A study of battery selection was conducted to draw the practicality of the BES sizing solutions.
