Due to the volatility and intermittence of wind generation, it is challenging to develop an economic dispatch algorithm for smart grids that not only meets the dynamic demand of electric energy, but also maximizes the benefits of energy suppliers using such renewable resource. In this paper, we account for smart grids with two categories of energy users, namely traditional energy users and opportunistic energy users, and address pricing and dispatch at one period of time (e.g., in hours). We model this problem as a stochastic programming problem that can be solved to determine the optimal day-ahead retail price, real-time price and the procurement of electricity energy.

Abstract Real time Demand-Response algorithm is a real time price (RTP) based demand response (DR) algorithm which helps in obtaining optimal control of load devices in a facility. We form a virtual electricity trading process, where energy management center (EMC) calculates the virtual retail prices and allots to each device, from which devices purchases energy. Here EMC acts as the leader and devices in the facility are followers. So the Stackelberg game between one-leader and M-followers is formulated to extract interactions between them, and optimization problems are formed for each player of the game to assist in finding the optimal strategy. We also demonstrated the unique Stackelberg equilibrium of the Stackelberg game which gives the optimal strategy or optimal energy demands for each device. The results of the simulation showed that Stackelberg game based DR algorithm is successful to get the optimal load control of device at all RTP throughout the day.

The integration of improved control techniques with advanced information technologies enables the rapid development of smart grids. The necessity of having an efficient, reliable, and flexible communication infrastructure is achieved by enabling real-time data exchange between numerous intelligent and traditional electrical grid elements. The performance and efficiency of the power grid are enhanced with the incorporation of communication networks, intelligent automation, advanced sensors, and information technologies. Although smart grid technologies bring about valuable economic, social, and environmental benefits, testing the combination of heterogeneous and co-existing Cyber-Physical-Smart Grids (CP-SGs) with conventional technologies presents many challenges. The examination for both hardware and software components of the Smart Grid (SG) system is essential prior to the deployment in real-time systems. This can take place by developing a prototype to mimic the real operational circumstances with adequate configurations and precision. Therefore, it is essential to summarize state-of-the-art technologies of industrial control system testbeds and evaluate new technologies and vulnerabilities with the motivation of stimulating discoveries and designs. In this paper, a comprehensive review of the advancement of CP-SGs with their corresponding testbeds including diverse testing paradigms has been performed. In particular, we broadly discuss CP-SG testbed architectures along with the associated functions and main vulnerabilities. The testbed requirements, constraints, and applications are also discussed. Finally, the trends and future research directions are highlighted and specified.

The electronic voltage transformer (EVT) has received much attention with the recent global trend to establish smart grids and digital substations. One of the main issues of the EVT is the deterioration of its performance with long-term operation which affects the control and protection systems it is employed for and hence the overall reliability of the power grids. This calls for the essential need for a reliable technique to regularly assess the accuracy of operating EVT in real-time. Unfortunately, traditional calibration methods cannot detect the incipient EVT performance change in real-time. As such, this paper presents a new online method to evaluate the accuracy of the EVT. In this regard, the Q-statistic is calculated based on the recursive principal components analysis (RPCA) using the output data of EVT to map up the changes of metering error on the electric–physics relationship. By employing the output data of the EVT along with the power grid characteristics, the performance of the EVT is evaluated without the need for a standard transformer, as per the current industry practice. Results show that the proposed method can assess the EVT with a 0.2 accuracy class.
