From the early seventies the Korean Government has adopted a rural industrialization policy as an important measure for promoting rural development. It has been perceived that through this measure the over-concentration of economic activity would be controlled and dispersed. Development of rural industrialization has passed through three different phases: i) the period of promoting rural cottage-type industries (1960-80); ii) the period of rural industrial park establishment; and iii) a stagnation period after the early 1990s. Throughout the overall period government policy changed from an individual project-oriented approach to a diversified and comprehensive policy program. The policy programs, such as the development of rural industrial parks, off-farm income source development and vocational training programs for farm youths, have helped in promoting rural industrialization. On the other hand, policy programs promoting rural out-migration and unbalanced regional development policy have impacted negatively on rural industrialization. Presently one of the serious policy issues facing rural industries is how to secure a young labor force and how to promote rural entrepreneurship. In addition, rural development efforts by local government and authorities are necessary in order to increase investment from urban-based entrepreneur firms.

The paper presents the results of the comparative analysis of operation modes of an autonomous hybrid power complex with/without the energy store. We offere the technique which defines the power characteristics of the main components of a hybrid power complex: the consumers of the electric power, wind power and photo-electric installations (the last ones have been constructed). The paper establishes that, in order to compensate the seasonal fluctuations of power in autonomous power systems with renewable energy resources, the accumulative devices are required, with a capacity of tens of MWh including devices that are capable to provide energy storage with duration about half a year. This allows abandoning the storage devices for smoothing the seasonal fluctuations in the energy balance.The analysis of operation modes of energy stores has shown that for a stock and delivery of energy on time intervals, lasting several hours, the accumulative devices with rather high values of charging and digit power aren't required. It allows using the lead-acid rechargeable batteries of the deep category for smoothing the daily peaks of surplus and a capacity shortage. Moreover, the analysis of operation modes of energy stores as a part of the hybrid complexes has demonstrated that in charging/digit currents of the energy store the low-frequency and high-frequency pulsations of big amplitude caused by changes of size of output power of the renewable power installations and loading are inevitable. If low-frequency pulsations (the period of tens of minutes) can partially be damped due to the restriction of size of the maximum charging current of rechargeable batteries, then it is essentially impossible to eliminate high-frequency pulsations (the period of tens of seconds) in the power systems with the only store of energy. The paper finds out that the combined energy store having characteristics of the accumulator in the modes of receiving and delivery of power on daily time intervals, and at the same time having properties of the supercondenser in the modes of reception and return of impulses of power on second intervals of time is best suited to requirements of the autonomous power complexes with renewable energy resources.
