This two-part paper deals with the coordination of the control actions in a network of many interacting components, where each component is controlled by independent control agents. As a case study we consider voltage control in large electric power systems, where ever-increasing pressures from the liberalization and globalization of the electricity market has led to partitioning the power system into multiple areas each operated by an independent Transmission System Operator (TSO). Coordination of local control actions taken by those TSOs is a very challenging problem as poorly coordinated operation of TSOs may endanger the power system security by increasing the risk of blackouts. This coordination problem involves many other issues such as communication, abstraction and last but not least optimization. This first part of the paper is devoted to the principals of the coordination control, addressing some of those issues using as a case study the problem of coordination control for avoiding voltage collapse in large-scale multi-area power systems.

Restructuring of electricity supply industry had begun in early 20th centuries. Malaysia Electricity Supply Industry (MESI) has aimed to change its structure to a wholesale market model in 2005. Started in 1992, Independent Power Producers (IPPs) were introduced and since then MESI had applied the Single Buyer Model until today. Even though, the Single Buyer Model had passed several process of evolution, it still a form of imperfect competition in which there is only one buyer and many sellers of a product. Therefore, other alternatives of electricity market model for MESI have been proposed, in order to carry on the MESI previous plan towards restructuring. This paper discusses three electricity market models; Single Buyer Market Model, Pool Market Model and Hybrid Market Model. The case study is carried out to compare the three market models in term of generation revenue. Data from 14 IPP and load profiles in MESI is used for the case study and the result will be discussed.

Abstract The CO2 emissions from a building’s power system will change over the life time of the building, and this need to be taken into account to verify whether a building is Zero Emission (ZEB) or not. This paper describes how conversion factors between electricity demand and emissions can be calculated for the European power system in a long term perspective through the application of a large scale electricity market model (EMPS). Examples of two types of factors are given: a conversion factor for average emissions per kWh for the whole European power system as well as a marginal factor for a specific region.

Abstract With the development of smart grid and energy internet, energy storage will play an important role in maintaining the power balance and providing frequency regulation in future power system. Consequently, energy storage faces a trade-off problem between the energy market and frequency regulation market. In this work, an operation model and strategy of energy storage to provide frequency regulation is proposed. Taking lithium battery as an example of energy storage, its technical feasibility to provide frequency regulation is firstly discussed. Then, a day-ahead energy market model in the power system is constructed to calculate the revenue of lithium battery. Finally, the operation strategy of lithium battery to provide secondary frequency regulation (namely AGC) is proposed based on the model of opportunity cost. Case study is conducted on a modified IEEE 6-bus system. It shows that the reduced marginal revenue of lithium battery in the energy market increases with the growth of its declared capacity for frequency regulation. Consequently, the optimal declared frequency regulation capacity for lithium battery is the amount, at which the reduced marginal revenue in the energy market is equal to the compensation price of frequency regulation.

Smart grids and the reliability of the power system issues are discussed in the paper. Smart Grids have emerged as a mean to increase the efficiency of energy systems around the world. Based on the analysis of Smart Grid implementation, liberalization of the electricity market and system reliability, it is concluded that Smart Grid has not improved the reliability of the power system The reliability can be improved only by constant investment in production and capital plants of the system, with optimal use of smart grids.. The paper presents the case study of disintegration of the power system under calm weather conditions, and case of low quality of power delivery where smart grids did not help enough.
