In the last few decades, more and more stress is put on the power supply and infrastructures because the power usage increased significantly. Especially, the rapid increase in cooling power usage is damaging to a grid stability. For such reasons, some policies like demand management program, which include limitation of air conditioning temperature have been implemented by the government for stabilizing power supply and the introduction of real-time electricity price has been considered as an active solution for the issue. However, the improper control of air-conditioner system is possible to cause some displeasures or discomforts of users and the lack of automatic load control systems to effectively control power consumption responding to real-time price are regarded as the major barriers for fully utilizing the potential benefits of the introduction of real-time pricing. In general, most of the current air-conditioner systems are manually operated by users and this makes it difficult for users to properly adjust their electricity consumption in response to the time-varying electricity price. Therefore, this study proposes an automated control strategy for the air conditioner system considering the indoor temperature and humidity. The proposed control strategy aims to minimize the electricity charges as well as guarantee user's comfort.

The installation of energy storage system can provide lots of advantage for load management such as load leveling, peak shaving, frequency and voltage control, and improvement of reliability in grid. Additionally, energy storage system can make end-users reduce their electricity expenditures, especially, for the educational service customer being charged by time of use electricity pricing(ToU). However, the recent studies have revealed that the high initial cost in energy storge system, the major barriers for the energy storage system installation. To maximize the economical efficency of energy storge system, the optimal capacity setimation method has been proposed in many other earlier studies, but this method did not consider the variation of power consumption and electricity estimation of energy storage system. Therefore we propose an optimal capacity capacity estimation method for energy storage system based on life cycle cost(LCC). The proposed method can estimate more realistic optimal capacity of energe storage system by considering the variation of power consumption and electricity price during th lifetime of energy storge system. In order to test the proposed method, we implemented this method to the Chunchen Campus of Kangwon National University.

In residential house, photovoltaic (PV) system among various alternatives in renewable energy system is the most efficient and feasible solution for reducing energy consumption and electricity cost. However, relatively high initial cost make people reluctant to install PV system in their houses. Therefore, in the initial state for PV system installation in the house, it is very important to decide proper capacity of the PV system considering the expected energy usage and solar energy supplying condition with the house. This paper proposes a novel optimization model for deciding appropriate capacity of the PV system for residential house. The objective function of the model is to minimize the annual cost including electricity bill, operation and maintenance cost, and annual fixed cost calculated from the initial installation cost based on capital recovery factor (CRF). The model also shows the optimal inclining angle of PV panels of the system. In this paper, we estimate the PV output using PVWATTS (PV simulator of Office of Energy Efficiency and Renewable Energy) and find optimal solutions by Sequential Quadratic Programming (SQP) method using MATLAB software. The proposed approach is finally applied to a residential model house in Gangneung, Gangwon-Do and verified its feasibility for adopting to PV system design for residential houses.

Recently, many actions are taking to accelerate progress toward social consensus and implementation of Smart Grid. Smart Grid refers to a evolution of the electricity supply infrastructure that monitors, protects, and intelligently optimize the operation of the interconnected elements including various type of generators, power grid, building/home automation system and end-use consumers. The most distinguished element will be Advanced Metering Infrastructure (AMI) that will be installed to every end-use consumer's home or building and optimize the energy consumption of the end-use consumer. The key function of AMI is energy management capability that coordinates and optimally controls the various loads according to the operating condition and environments. In this study, we figure out the basic function of AMI in Smart Energy House that can be defined as a model house implementing in Smart Grid. This paper proposes the energy management algorithm that will be implemented in AMI at Smart Energy House. The paper also show how energy saving in Smart Energy House can be achieved applying the proposed algorithm to an actual house model that has mainly lighting, air-conditioning, TV loads.
